Hanna Instruments thermometer for temperature over a wide range with a type K thermocouple, one model.
HI935005
This Hanna Instruments thermometer measures temperature over a wide range with a type K thermocouple.
A thermocouple measures temperature from the voltage generated where two dissimilar metals meet. It has almost no mass, so it follows a changing temperature almost instantly — which is what a food probe has to do. Type K covers the widest range of the common types, which is why it is the default for anything that gets genuinely hot.
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.
Thermocouple wire is polarised and the two conductors are different alloys; a probe wired backwards reads a temperature moving the wrong way.
Supplied as one model.
