Short answer

A temperature data logger calibration log records each logger's identity, the traceable reference probe, and the as-found and as-left readings at each calibration point, so sensor drift is caught. Food, pharmacy and cold chain teams use it, usually every 12 months as a common practice. Food Standard 3.2.2 clause 22 requires premises handling potentially hazardous food to have a thermometer accurate to plus or minus 1 degree C.

Checked against Food Standard 3.2.2 (Compilation F2025C00834, effective 2025-08-13, registered 2025-09-05; current as at 2026-10-26 (Federal Register of Legislation)) on by the MapTrack templates team. How we check templates

Key takeaways

  • The MapTrack temperature data logger calibration log template contains 30 checks across 6 sections. Sections covered: Reference standards & setup, Ice point check, Boiling point check, Working range test points, Drift analysis, Certification & labelling.
  • Food Standard 3.2.2 clause 22 sets the only legal accuracy figure here: plus or minus 1 degree C for the food premises thermometer.
  • Temperature control means 5 degrees C or below, or 60 degrees C or above, unless another temperature is shown to be safe (clause 1).
  • A 12-month interval is common practice for food loggers; set pharmaceutical intervals from your quality system and the manufacturer, and shorten either when drift nears tolerance.
  • Record as-found readings before adjusting: an out-of-tolerance logger puts every reading since its last calibration in question.
  • Use a reference probe with a current traceable certificate; AS ISO/IEC 17025:2018 is the standard calibration laboratories are accredited against.

What is a temperature data logger calibration log template?

A temperature data logger calibration log is a formal record used to document the periodic calibration of an NTC, PT100 or thermocouple data logger against traceable reference probes. The log captures the instrument identity, the reference probe used, the data logger sensor type, the rated accuracy class (typically plus or minus 0.5 degrees Celsius for food cold chain duty and plus or minus 0.2 degrees Celsius for pharmaceutical cold chain duty), and the as-found and as-left readings at each calibration point. Standard practice covers an ice-point check at 0 degrees Celsius, a boiling-point check at 100 degrees Celsius corrected for calibrated barometric pressure, and a 3-point comparison sweep against a reference probe across the rated working range. Sensor drift over the 12 month interval is then trended against previous calibration sheets to flag a logger that has aged out of its accuracy class.

From a regulatory angle, temperature data logger calibration sits inside a tight framework that food safety auditors, pharmaceutical quality teams and HACCP coordinators rely on for cold chain integrity evidence. Food Standard 3.2.2 in the Australia New Zealand Food Standards Code requires food businesses that handle potentially hazardous food to have a readily accessible temperature measuring device accurate to plus or minus 1 degree Celsius (clause 22). NATA accreditation provides the practical pathway to a traceable calibration certificate. AS ISO/IEC 17025 sets the international competence standard for the calibration laboratory or in-house procedure that issues the certificate, with traceability through the National Measurement Institute. TGA cold chain guidelines require monitoring equipment to be calibrated and traceable for vaccine, blood bank and pharmacy storage. A documented calibration log is the artefact food safety auditors, TGA inspectors and HACCP coordinators will look for first when they question the integrity of a temperature reading on a food cold chain, pharma cold chain or vaccine distribution run.

Benefits of using this temperature data logger calibration log template

  • Cold chain integrity assurance: documented calibration confirms data logger readings are accurate before they are used as cold chain evidence under Food Standard 3.2.2 guidelines
  • HACCP compliance: critical control point monitoring requires data loggers to be calibrated and traceable before readings can be used for cooking, cooling or chilled storage
  • Regulatory compliance: AS ISO/IEC 17025 and NATA accreditation require monitoring equipment to be calibrated against a traceable reference, with records maintained for audit and investigation
  • Detect sensor drift early: trended as-found readings against the reference probe reveal NTC, PT100 or thermocouple drift before the logger falls outside its accuracy class
  • Ice-point and boiling-point verification: the dual fixed-point check intercepts sensor offset or span error before it skews a reading at the critical temperature band
  • 3-point comparison rigour: comparison against a reference probe at low, mid and high points confirms linearity across the working envelope, not just at fixed points
  • Sensor-type discipline: separate calibration records for NTC, PT100 and thermocouple loggers force the right calibration procedure to be applied to the right sensor type
  • Due diligence record: after a cold chain breach or vaccine spoilage event, a stamped log proves the data logger was verified at monitoring time

What to include in a temperature data logger calibration log template

This temperature data logger calibration log template covers 11 key areas:

  • Instrument details: make, model, serial number, asset/ID, sensor type (NTC, PT100 or thermocouple), accuracy class and rated working range
  • Reference probe details: make, model, serial number and NATA-traceable certificate number of the reference probe, four times better than the data logger accuracy class
  • Environmental conditions: ambient temperature, relative humidity and barometric pressure recorded against the calibration event for boiling-point correction
  • Ice-point check at 0 degrees Celsius: as-found and as-left logger readings against an ice slurry of distilled water and shaved ice, against accuracy class
  • Boiling-point check at 100 degrees Celsius: as-found and as-left logger readings against rolling boiling distilled water corrected for barometric pressure on the day of calibration
  • 3-point comparison sweep: as-found and as-left logger readings against the reference probe at three test points across the rated working range envelope
  • Sensor drift over 12 months: comparison of current as-found readings against the previous calibration sheet to flag a logger that has aged out of class
  • Adjustment notes: details of any zero, span or linearity adjustment made during the calibration, with the as-left readings clearly distinguished from the as-found readings
  • Application category sign-off: confirmation that the data logger accuracy class is fit for the application, with a note for category changes since the previous calibration
  • Technician identity and sign-off: cold chain coordinator or pharmaceutical quality technician name, qualification number, calibration date and signature confirming the logger is fit for service
  • Calibration history register: 8-row table capturing date, calibrated by, next due, overall result and NATA certificate number for each event over instrument life

How to use this temperature data logger calibration log template

  1. 1. Record the instrument details: fill in make, model, serial number, sensor type, accuracy class and rated working range at the top of page 1, cross-reference against the cold chain instrument register to confirm the data logger identity and application category before any reference probe is connected
  2. 2. Record the reference probe: capture make, model, serial number and NATA-traceable certificate number of the reference probe, confirm the reference accuracy is at least four times better than the data logger accuracy class and that the reference certificate is current
  3. 3. Stabilise the logger: allow the data logger and reference probe to sit at the calibration room ambient temperature for at least 30 minutes before testing, log the ambient temperature, relative humidity and barometric pressure, and replace the logger battery if condition warrants it
  4. 4. Run the ice-point check: prepare an ice slurry from shaved distilled water ice and a small volume of distilled water, immerse both the logger probe and the reference probe to the rated immersion depth, allow 5 minutes for stabilisation and record the as-found logger reading against the reference
  5. 5. Run the boiling-point check: bring a beaker of distilled water to a rolling boil on a controlled heat plate, immerse both probes to the rated immersion depth, allow 5 minutes for stabilisation and record the as-found logger reading against the reference corrected for the calibrated barometric pressure
  6. 6. Run the 3-point comparison sweep: place both probes in a calibrated dry block or temperature-controlled bath at the low, mid and high points of the rated working range in turn, allow 5 minutes for stabilisation at each point and record the as-found logger reading against the reference
  7. 7. Compare against previous calibration: pull the previous calibration sheet from the asset record in MapTrack, compare current as-found readings to the previous as-left readings at each test point and calculate sensor drift over the 12 month interval to flag an aged logger
  8. 8. Adjust if required and re-test: if any test point falls outside the accuracy class, perform the manufacturer-specified adjustment or send the data logger for factory calibration, then repeat the ice-point, boiling-point and 3-point sweep and record the as-left readings
  9. 9. Close the record: stamp the calibration sheet with the technician name and qualification number, set the next calibration due date based on the application interval, attach a NATA-traceable calibration sticker to the logger body and load the certificate against the asset in MapTrack

In MapTrack, you can automate compliance tracking and audit trails. Each submission is stored as a timestamped PDF against the asset record.

How often should you complete this calibration log?

Temperature data logger calibration intervals are driven by the cold chain application and the accuracy class required. For food cold chain monitoring under Food Standard 3.2.2 at plus or minus 0.5 degrees Celsius accuracy, the typical interval is 12 months from the previous calibration sticker. For pharmaceutical cold chain duty at plus or minus 0.2 degrees Celsius accuracy under TGA cold chain guidelines, the interval tightens to 6 months because vaccine, blood bank and pharmacy storage tolerances are tighter. For HACCP critical control point monitoring on cooking, cooling and hot-holding loops, the interval is typically 12 months but is often supplemented by a monthly user verification check against a calibrated reference thermometer to catch sensor drift between formal calibrations. Outside the scheduled cadence, a temperature data logger must also be calibrated immediately after a suspected impact, water ingress, battery failure, suspected cold chain breach or extended storage period that puts the sensor outside its rated working range.

Frequently asked questions

A temperature data logger calibration log should record the instrument identity covering make, model, serial number, asset number, sensor type, accuracy class and rated working range. It should then record the reference probe identity and NATA-traceable certificate number, ambient temperature, humidity and barometric pressure, the ice-point check at 0 degrees Celsius, the boiling-point check at 100 degrees Celsius corrected for barometric pressure, and as-found and as-left readings at three test points across the working range against a reference probe. Sensor drift comparison against the previous calibration sheet, application category sign-off, technician sign-off with qualification number and the next calibration due date complete the record.

For food cold chain monitoring under Food Standard 3.2.2 at plus or minus 0.5 degrees Celsius accuracy, the typical interval is 12 months from the previous calibration sticker. For pharmaceutical cold chain duty at plus or minus 0.2 degrees Celsius accuracy under TGA cold chain guidelines, the interval tightens to 6 months because vaccine, blood bank and pharmacy storage tolerances are tighter. For HACCP critical control point monitoring, the interval is typically 12 months supplemented by a monthly user verification against a calibrated reference thermometer. Outside the scheduled cadence, calibrate immediately after impact, water ingress, battery failure or a suspected cold chain breach.

The anchor standards are Food Standard 3.2.2 in the Australia New Zealand Food Standards Code, which requires a readily accessible temperature measuring device accurate to plus or minus 1 degree Celsius where potentially hazardous food is handled, AS ISO/IEC 17025 for the international competence standard on calibration laboratories including traceability to the National Measurement Institute, NATA accreditation as the practical pathway to a traceable calibration certificate, and TGA cold chain guidelines for vaccine, blood bank and pharmacy storage. The HACCP framework sits over the top for food safety critical control point monitoring evidence.

An NTC thermistor data logger uses a temperature-sensitive resistor and is well suited to cold chain monitoring at plus or minus 0.5 degrees Celsius accuracy for food and general logistics duty. A PT100 platinum resistance data logger uses a platinum element and offers higher accuracy at plus or minus 0.2 degrees Celsius for pharmaceutical cold chain, vaccine storage and blood bank duty. A thermocouple data logger uses dissimilar metal junctions and is well suited to high-temperature monitoring on cooking, hot holding or industrial process loops where the NTC and PT100 working range is exceeded. The calibration log captures the sensor type so the right calibration procedure and accuracy class are applied.

Yes, the temperature data logger calibration log is free to download as a PDF and free to use across your cold chain instrument register. MapTrack publishes the calibration log as a stand-alone working document with no signup required.
