Hanna Instruments thermometer for temperature with a thermistor sensor rather than a thermocouple, one model.
HI93501
This Hanna Instruments thermometer measures temperature with a thermistor sensor rather than a thermocouple.
A thermistor is more accurate than a thermocouple over the narrow range that food safety cares about, and it needs no cold-junction compensation. It responds more slowly, which is a fair trade when the reading is a chilled cabinet rather than a grill.
Most wrong temperatures are not the instrument's fault. A probe placed too shallow, read before it settled, or put in the thinnest part of a piece of food gives a confident number that was never true of the product.
Insert to the depth marked, into the thickest part, and wait for the reading to stop moving. Check the instrument against an ice-water slurry periodically — that is a real reference point, and it costs nothing.
Give a thermistor probe time to settle; reading it too early is the most common way to record a temperature that was never reached.
Supplied as one model.
