The probe thermometer more accurate instead of infrared thermometer the reason because the probe must be inserted the full length of the sensing area. The infrared thermometers are used to measure the surface temperature. It cannot be used to measure the internal temperature of food.
Probe thermometer will give the actual temperature of the product, as the infrared thermometer will measure the packaging itself.
The difference if using a proper calibrated thermometer will be minimal, in case of high deviation this means that one is giving bad result.
There is a new technology to measure product temperature where a data loger is added inside the product to measure all cold chain of the product during distribution.
Both are important. Infrared thermometer is very useful during receiving the item though it raw food items specially to the point of faster & safe. Prob thermometer majority using to check the cooked food temperature.
well both could be accurate depend on the companies of thermometer.
Infrared thermometers are very fast (instantaneous), provide a good indication,
For measuring food temperature probe thermometer is more accurate as compare to infrared thermometer. Probe thermometer measures the internal temperature of any food item which is highly critical in food safety while infrared thermometer is best used for measuring aerial or environmental temperature.
Probe thermometer is more accurate than Infrared thermometer because Infrared just observed surface temperature but prob inserted in the food and gives internal temperature
.
infrared thermometer is faster and safety
