Point the thermometer straight down into the bottom of the comparator and take a measurement. The instrument should read within 1 °C of the Reference Thermometer at 22°C ambient room temperature, depending on the accuracy of the thermometer.

How do I reset my thermal scanner?

The first reset is the ice point method.

  1. Fill a glass with crushed ice.
  2. Add a little clean water until the glass is full and stir.
  3. Wait for about three minutes before inserting the sensor on the thermometer into the ice-filled water.
  4. Wait for about thirty seconds and check that the thermometer reads 32°F.

between 91F and 94F
It would be normal to read an actual forehead skin surface temperature between 91F and 94F if using a general-purpose infrared thermometer. Some infrared thermometers have an “adjustable emissivity feature”. Some are factory set for emissivity of 0.95, or in the case of our IRFS, 0.97.

Do Infrared Thermometers have to be calibrated?

Infrared thermometers cannot typically be calibrated at home, but they are known for their low drift. If the results of your ice bath test are within your unit’s manufacturer’s listed specification, you are good to go.

How do you calibrate a non contact forehead infrared thermometer?

This can be achieved in a few different ways. However, the simplest way to help calibrate a non-contact thermometer is to create an ice bath for the thermometer to measure. Luckily, this can be done by using a large glass rather than having to fill up an entire bathtub.
