So if you find the ℃/℉ button on your thermometer, just press it to.

How to calibrate a infrared thermometer. Insert the thermometer into the slurry and wait at least one to two minutes for the reading to stabilise. Add very cold water until the water. Fill a glass with ice cubes, then top off with cold water.

This could take any amount of time, depending on the response time of the inserted probe. How do you set a thermometer? To calibrate your infrared thermometer with an ice bath:

Stir the water and let sit for 3 minutes. Hold the meter by its handle grip and point it toward the surface to be measured. Fill a large glass to the very top with ice (crushed ice is preferred but not required).

Stir the ice slurry vigorously and let stand for approx 5 minutes. This usually takes a minute or less. This is hard to do though, because surfaces generally don’t have a fixed emissivity.

It is best to calibrate your infrared thermometer. Ensure the dut infrared thermometer has been in the calibration ambient conditions for at least one hour (an important part of ir thermometer accuracy is internal temperature,. Pull and hold the trigger to turn the meter on and begin testing.

The thermometer is accurate if it registers 32° f or 0° c. The solution is a radiometric calibration on your surface. Aim the infrared thermometer vertically in to the comparator pot as close as possible, and compare the readings.
