The accuracy of all electronic instruments is affected by the temperature of the environment in which they are being used. Large changes in the ambient temperature can introduce error in the readings of the device. This is also true for infrared thermometers. When an IR thermometer is taken into a refrigerated space, the readings may be as much as 5 or 6 degrees off. The graph above shows what happens when we took four different IR thermometers from normal room temperature into a space that was 50ºF lower. If the... Read Now
What is an IP Rating?
