About this checklist
What this checklist helps you verify
Verify that temperature devices are uniquely identified, checked against approved references, within tolerance, correctly labelled, and removed from service when accuracy is uncertain.
When
Scheduled calibration, after damage, and after suspect readings
Use it during routine calibration, after impact or repair, after failed verification, before critical use, and when device readings disagree unexpectedly.
Who
Cold-chain, quality, maintenance, and technical teams
Cold-chain, quality, maintenance, metrology, warehouse, and approved service teams can perform or own applicable checks.
Outcome
Clear device status, evidence, and verified return to service
Create one evidence trail for standards, readings, tolerance, adjustment, failure, labels, certificates, actions, and final release.
Complete thermometer and sensor calibration checklist
10 sections. 60 practical calibration checks.
Adapt the checks to your device type, measurement range, reference standard, calibration method, tolerance, quality programme, and approved service requirements.
Section 1Calibration scope and device inventory
- Confirm site, area, calibration date, device population or sample, and thermometer or sensor calibration scope are clearly identified.
- Record device type such as handheld thermometer, probe, data logger, fixed sensor, recorder, vehicle sensor, wireless sensor, or another approved instrument.
- Record asset ID, serial number, manufacturer, model, measurement range, location, and equipment or process served.
- Identify the approved calibration interval, verification frequency, tolerance, and responsible owner for each device type.
- Review previous out-of-tolerance results, repairs, dropped devices, damaged probes, battery failures, communication faults, and overdue actions.
- Record the current device status as serviceable, verification due, calibration due, hold, repair, or remove from service.
Section 3Device identity, condition, and pre-check
- Verify the physical device ID and serial number match the calibration record and asset register.
- Inspect housing, display, buttons, probe, cable, connector, sensor tip, mounting, seals, and protective covers for damage or deterioration.
- Check battery, power supply, charging, signal, communication, memory, alarm display, and other basic functions before calibration.
- Review the device's most recent calibration label, due date, certificate, adjustment history, and previous tolerance result.
- Clean or condition the device and probe using the approved method before testing where required.
- Remove or hold devices with broken probes, unreadable displays, damaged cables, loose connectors, water ingress, or other defects affecting safe calibration.
Section 5Mid-point calibration check
- Stabilize the device and reference at the approved mid-range test point before recording readings.
- Record the reference reading and device reading after stabilization.
- Calculate or record the difference between the device and reference.
- Compare the difference with the approved mid-point tolerance.
- Repeat or confirm the reading where required to verify repeatability and stable response.
- Escalate mid-point drift, nonlinearity, unstable response, or other results outside the approved tolerance.
Section 7Adjustment, recalibration, and failure control
- Adjust the device only when adjustment is permitted by the approved procedure and authorized personnel.
- Record the as-found result before adjustment so the original condition remains traceable.
- Repeat the required calibration points after adjustment to verify the device now meets tolerance.
- Identify equipment, stock, processes, or records potentially affected by an out-of-tolerance device when required by the quality programme.
- Quarantine, repair, replace, downgrade, or remove the device from service when it cannot meet the approved acceptance criteria.
- Create corrective actions for repeated drift, frequent recalibration, physical damage, poor storage, user handling, or recurring device failure.
Section 9Storage, handling, placement, and ongoing verification
- Check calibrated thermometers, probes, loggers, and sensors are stored or mounted to protect them from impact, moisture, contamination, and unauthorized adjustment.
- Verify fixed sensors remain in the approved location and have not been moved, blocked, insulated, or exposed to abnormal airflow without review.
- Check portable probes are cleaned, protected, and handled so the sensor tip and cable are not damaged between uses.
- Confirm devices used for critical monitoring receive the approved interim verification or reasonableness check between full calibrations.
- Review discrepancies between manual and automated devices for signs of drift, placement error, poor contact, or sensor failure.
- Escalate repeated handling damage, unauthorized relocation, missed verification, or other practices that could undermine calibrated accuracy.
Section 2Reference standard and calibration setup
- Identify the reference thermometer, simulator, dry-block, bath, ice point, certified standard, or other approved calibration reference used for the check.
- Verify the reference standard has current traceable calibration or other approved evidence suitable for the required accuracy.
- Check the reference range and resolution are appropriate for the device and temperature points being tested.
- Confirm the calibration environment, setup, immersion depth, stabilization time, sensor placement, and test method follow the approved procedure.
- Inspect leads, probes, connectors, wells, baths, blocks, fixtures, and accessories used in the setup for damage or contamination.
- Do not proceed when the reference standard, setup, environment, or procedure cannot support a reliable calibration decision.
Section 4Low-point calibration check
- Stabilize the device and reference at the approved low-temperature test point before recording readings.
- Record the reference reading and device reading after the required stabilization period.
- Calculate or record the difference between the device and reference using the approved method.
- Compare the difference with the approved low-point tolerance for the device and intended use.
- Repeat the reading when required to confirm stability and rule out transient or setup-related error.
- Escalate low-point results outside tolerance or unstable readings that cannot be justified by the approved procedure.
Section 6High-point calibration check
- Stabilize the device and reference at the approved high-temperature test point before recording readings.
- Record the reference reading and device reading after the required stabilization period.
- Calculate or record the difference between the device and reference using the approved method.
- Compare the result with the approved high-point tolerance and device specification.
- Check the device returns to stable operation after the high-point exposure where the procedure requires it.
- Escalate high-point error, slow response, drift, display fault, or other out-of-tolerance result affecting intended use.
Section 8Calibration labels, certificates, and records
- Apply or update the calibration label with device ID, calibration date, next due date, status, and other required information.
- Ensure the label is legible, securely attached, and does not obscure the display, sensor, regulatory marking, or other required information.
- Complete the calibration record with reference standard, method, test points, readings, tolerance, result, adjustment, operator, and approval where required.
- Verify calibration certificates or service reports identify the correct device and include the evidence required by the programme.
- Update the asset register, maintenance system, quality record, WMS or other equipment record with the new calibration status.
- Escalate missing certificates, conflicting due dates, incomplete readings, wrong device IDs, or records that cannot support traceability.
Section 10Corrective actions and final release
- Classify findings by reference standard, device condition, low-point result, mid-point result, high-point result, adjustment, label, record, or other approved category.
- Prioritize findings using measurement error, product risk, process impact, affected duration, recurrence, device criticality, and use since last acceptable check.
- Create corrective actions with named owners, due dates, repair or replacement scope, affected-product review, evidence expectations, and verification criteria.
- Confirm any out-of-tolerance device has a documented disposition and is clearly prevented from normal use until acceptable status is restored.
- Verify recalibrated or replacement devices meet the required tolerance before return to service.
- Record final calibration status, critical open issues, next due date, technician or operator, quality or maintenance owner, and approval where required.
