Food temperature probe calibration: a practical guide for commercial kitchens
A temperature reading is only useful if the probe can be trusted. Regular probe checks, good cleaning practice and a clear record help kitchen teams show that temperature monitoring is meaningful.
Why should a food probe be checked?
The Food Standards Agency says it is essential to know that a probe is working properly so its readings can be relied on. Businesses should follow the manufacturer’s instructions for how often a particular probe should be checked.
A simple routine check can also help identify a damaged or inaccurate probe before unreliable readings become part of the kitchen record.
How can you check a digital food probe?
FSA Safer Food, Better Business guidance describes a simple check using iced water and boiling water. The probe should read between -1°C and 1°C in iced water and between 99°C and 101°C in boiling water.
If the reading is outside the expected range, the FSA guidance says the probe should be replaced or returned to the manufacturer for calibration. Take care when carrying out any boiling-water check and follow the probe manufacturer’s instructions.
Cleaning the probe matters too
A probe can transfer contamination between foods if it is not cleaned and disinfected appropriately. FSA guidance says to clean and disinfect the probe between uses.
Store probes safely and protect them from damage, extreme temperatures and liquids when they are not in use.
Should you record probe checks?
A simple record of the probe, date, check result and any corrective action gives managers evidence that the measuring equipment behind their food-temperature records is being monitored.
TKEG includes digital probe and calibration records alongside fridge, freezer, heating and cooling records.
Connect probe checks to your digital temperature records
A probe check is most useful when it forms part of the same system as the temperatures being measured. TKEG connects probe records with wider kitchen compliance and due-diligence evidence.

Common questions
How often should a food temperature probe be calibrated?
There is not one universal interval for every probe. Follow the manufacturer’s instructions and your food-safety management procedures, and check the probe regularly.
What should a probe read in iced water?
FSA SFBB guidance gives an expected range of -1°C to 1°C for the simple iced-water check.
What should a probe read in boiling water?
FSA SFBB guidance gives an expected range of 99°C to 101°C for the simple boiling-water check.
What if my probe is outside the expected range?
FSA guidance says to replace it or return it to the manufacturer to be calibrated rather than relying on inaccurate readings.
