When to use this sheet
Use this to record the iced-water and boiling-water check for a named probe. It is the check Safer Food, Better Business describes under extra checks, not a laboratory certificate.
How to complete it
Write the probe, the date, the iced-water reading and the boiling-water reading you saw, and whether you kept the probe in use. Safer Food, Better Business uses −1°C to 1°C in melting ice and 99°C to 101°C in boiling water.
What this does not replace
It does not replace the manufacturer’s instructions, a certificate for a different instrument, or the daily food-temperature check.
