Infrared thermometer calibration
An infrared thermometer must be calibrated so that it correctly indicates the temperature of the target being measured. If the pyrometer used has a temperature measurement super
In order to measure the temperature, aim the instrument at the object to be measured, press the trigger to read out the temperature data on the LCD of the instrument, make sure to arrange the ratio of distance and spot size, and the field of view. There are a few important things to remember when using an infrared thermometer:
Only the surface temperature is measured, infrared thermometers cannot measure internal temperatures. Temperature measurements cannot be taken through glass, which has very specific reflective and transmissive properties that do not allow for accurate infrared temperature readings. However, temperatures can be measured through an infrared window. Infrared thermometers are preferably not used for temperature measurement on shiny or polished metal surfaces (stainless steel, aluminum, etc.). Locate the hot spot, to find the hot spot, the instrument is aimed at the target, and then make an up and down scanning movement on the target, until the hot spot is identified. Pay attention to the environmental conditions: steam, dust, smoke, etc.. It blocks the optical system of the instrument and affects the accurate temperature measurement. Ambient temperature, if the pyrometer is suddenly exposed to an ambient temperature difference of 20 degrees or higher, allow the instrument to adjust to the new ambient temperature within 20 minutes.
How to calibrate an infrared thermometer
In the black body radiation source, with a second-class or higher standard thermocouple, photoelectric pyrometer or accuracy level higher than the calibrated infrared thermometer infrared thermometer as a standard, tuning can be.
All objects with temperatures above absolute zero are constantly emitting infrared radiation energy into the surrounding space. The size of the object's infrared radiation energy and its distribution by wavelength - and its surface temperature has a very close relationship.
Therefore, through the measurement of the infrared energy radiated by the object itself, it will be able to accurately determine its surface temperature, which is based on the objective basis of infrared radiation temperature measurement.
