The infrared thermometer measures the surface temperature of an object. The unit’s optics sense emitted, reflected, and transmitted energy which is collect and focused onto a detector.

The unit’s electronics transmitted energy, which is display on the unit. For increased ease and accuracy the laser pointer makes aiming even more precise.

Infrared thermometer how to use

Infrared thermometers (temperature laser guns) give you a means to take the temperature of objects that are too difficult or dangerous to access otherwise, by using an infrared beam to collect the amount of transmitted, reflected and emitted energy off an object. Electronic sensors in the temperature gun convert these values into a measurement of the heat energy from the object (temperature).

Theory of measurement

Every object emits infrared energy in accordance with its temperature. By measuring the amount of this radiant energy, it is possible to determine the temperature of the emitting object.

Facts about infrared waves

Infrared radiation is a form of light (electromagnetic radiation) and has the property that it passes easily through the air while it is easily absorbed by solid matter.
With an emission thermometer that operates by detecting infrared radiation accurate measurement is possible, irrespective of the air temperature or the measurement distance.

Infrared radiation thermometer

Infrared radiation which has been emitted from the object is focused upon an infrared radiation sensor, via an optical system. This includes a lens that is transparent to infrared radiation. And 5.3µm cut off filter. The output signal from the infrared radiation sensor is input to an electronic circuit along with the output signal from a standard temperature sensor (Thermopile).

Infrared energy

All objects emit invisible infrared energy. The amount of energy emitted is proportional to the object’s temperature and its ability to emit IR energy. This ability, called emissivity, is based upon the material that the object is made of and its surface finish. Emissivity values range from 0.10 for a very reflective object to 1.00 for a black body. Factory set an emissivity value of 0.95, which covers 90% of typical applications.

  • If the surface to the measured is covered by frost or
    other material, clean it to expose the surface.
  • If the surface to be measured is highly reflective, apply
    masking tape or matt finish black paint to the surface.
  • If the meter seems to be giving incorrect readings check the front cone. There may be condensation or debris obstructing the sensor; clean per instructions in the maintenance section
