Generally speaking they come in two main classifications.
Temperature measuring devices for food.
The main advantage of this device is it does not use any power source for their operation.
This is especially important for big dishes like a whole turkey or chicken when you want to be sure that the heat of the oven has cooked all the way to the centre of the food.
So that we can easily use it to measure high temperatures.
Testo 112 high precision temperature measuring instrument is ideal for official control measurements carried out by food inspectors assessors and authorities.
Check the temperature of thin foods like hamburgers.
Traditional contact thermometers are increasingly being replaced in the food industry by non contact infrared temperature sensors pyrometers which offer an instantaneous response time the ability to measure moving objects and because there is no need to touch the measured object improved hygiene.
Place 2 2 deep in thickest part of food can be used in roasts casseroles and soups temperature is averaged along probe from tip to 2 3 up the stem cannot measure thin foods unless inserted sideways.
Thermometers are well known liquid expansion devices also used for temperature measurement.
A resistance thermometer is a temperature measuring instrument consisting of a sensor an electrical circuit element whose resistance varies with temperature a framework on which to support the.
The scale must be in 1 c increments.
The mercury type and the organic usually red liquid type.
A bimetal bayonet style thermometer with a dial face scale with a range of 18 to 105 c 0 to 220 f may be used for certain applications in food temperature measurement.
But these are not so accurate like electrical devices such as thermocouple.
Once you insert a food thermometer you can measure the internal temperature of the food.
Measuring the temperature of products inside ovens and roasters.
