Hanna Instruments thermometer for type K temperature to a tenth of a degree, one model.
HI93531N
This Hanna Instruments thermometer measures type K temperature to a tenth of a degree, with field calibration.
A calibration button lets the instrument be checked against ice water and corrected on the spot, which is what an audit asks for. Without it a drifting thermometer has to be sent away or thrown away.
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.
Ice water is a genuine 0 °C reference only when it is a slurry of crushed ice and water, stirred — not ice cubes in a glass.
Supplied as one model.
