Digital infrared thermometers (DITs) are becoming a standard feature in the home, but can you tell how much heat you’re putting on the walls and floors?

The answer is no.

There are two ways to test a DIT.

The first is to turn the device on and see how much it heats the wall and floor.

The second is to run the DIT on a temperature sensor, like a thermometer, and see if the readings fall within a range you’re comfortable with.

We’re going to look at both methods, and how the DITT works, in this post.
