Thermometer Accuracy Verification (Free)
Form – Thermometer Accuracy Verification
A thermometer that’s wrong makes every temperature record it’s touched wrong. This form structures the routine accuracy checks – ice point, and boiling point where relevant – with clear tolerances.
Be specific and honest in every field; vague records help nobody during an investigation. If a field doesn’t apply, write N/A rather than leaving it blank.

1. Instrument
- Thermometer ID: | Type: [probe / infrared]
- Location/use: | Date: [YYYY-MM-DD] | Checked by: [Name]
- Probe cleaned/sanitized before check? [Y/N]
- Stabilization time allowed? [Y/N]
- Ambient conditions:
- Reference thermometer ID (if comparative check):
- Tolerance: [e.g., +/-0.5 °C at ice point]
2. Checks
| Check | Reference | Reading | Tolerance | Pass / Fail |
|---|---|---|---|---|
| Ice point | [Crushed ice + water, stabilized] | °C | [+/-0.5 °C] | |
| Boiling point (if applicable) | [Rolling boil, altitude-corrected: °C] | °C | [+/-1.0 °C] | |
| Post-repair verification (if applicable) | [N/A or details] | °C |
3. Outcome
A failed thermometer means questioning everything it measured since its last pass – that’s the real cost of skipping checks. Remove it from use immediately and assess the impact before you decide it’s ‘probably fine’.
- Result: [Pass – return to use / Fail – remove from use]
