What Is a Digital Infrared Thermometer?

In nature, all objects whose temperature is above absolute zero constantly emit infrared radiation energy to the surrounding space. The amount of infrared radiation energy of an object and its distribution by wavelength are very closely related to its surface temperature. Therefore, by measuring the infrared energy radiated by the object itself, it can accurately determine its surface temperature, which is the objective basis on which infrared radiation temperature measurement is based.

A black body is an idealized radiator that absorbs radiant energy of all wavelengths without reflection and transmission of energy.

The infrared thermometer must be calibrated so that it can correctly display the temperature of the target being measured. If used

Infrared temperature measurement technology plays an important role in the production process in product quality control and monitoring, equipment online fault diagnosis and safety protection, and energy conservation. For almost 20 years, non-contact

In order to measure the temperature, point the instrument at the object to be measured, and read the temperature data on the LCD of the instrument according to the trigger to ensure that the ratio between the distance and the spot size and the field of view are arranged.

Matters needing attention when using infrared thermometer:

1. Only the surface temperature is measured. The infrared thermometer cannot measure the internal temperature.

2. Temperature cannot be measured through glass. Glass has very special reflection and transmission characteristics, and accurate infrared temperature readings are not allowed. However, the temperature can be measured through an infrared window. Infrared thermometer is best

Not for temperature measurement on shiny or polished metal surfaces (stainless steel, aluminum, etc.).

3. Locate the hotspot. To find the hotspot, the instrument aims at the target, and then scans up and down on the target until it is determined.

4. Pay attention to environmental conditions: steam, dust, smoke, etc. It blocks the optical system of the instrument and affects accurate temperature measurement.

5. Ambient temperature. If the thermometer is suddenly exposed to a temperature difference of 20 ° C or higher, allow the instrument to adjust to the new ambient temperature within 20 minutes.
