We use infrared thermometer in our daily life, it uses the principle of infrared radiation emitted by the object has the radiant energy into electrical signals, the size of infrared radiation and the object itself corresponds to the temperature, according to the size of the electrical signals converted into the temperature of the object (such as steel) can be determined. Handheld infrared thermometer by the optical system, photoelectric detector, signal amplifier and signal processing, display output and other components. So, what is the use of infrared thermometer ar300? What is the working principle of infrared thermometer?
Infrared thermometer ar300 use
Infrared thermometer can not be measured through the glass, glass has a very special reflective and transmittance characteristics, does not allow accurate infrared temperature readings. However, temperatures can be measured through an infrared window. Infrared thermometers are best not used for temperature measurement on shiny or polished metal surfaces (stainless steel, aluminum, etc.).
The infrared thermometer red point to the object to be measured, press the temperature button, the temperature data read out on the thermometer's LCD, to ensure that the arrangement of the distance and spot size ratio, and field of view. 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.
Infrared thermometer only measures the surface temperature, infrared thermometer can not measure the internal temperature. It blocks the instrument's optical system and affects accurate temperature measurement. If the pyrometer is suddenly exposed to an ambient temperature difference of 20 degrees Celsius or higher, allow the instrument to adjust to the new ambient temperature within 20 minutes.
Infrared thermometer in the use of the following precautions: In order to avoid damage to the infrared thermometer, the use of compressed air to remove large particles and dust, and then wipe with a piece of cloth. Use a clean computer monitor cleaning cloth to gently wipe the display, use a clean and slightly wet cloth to gently wipe the body of the pyrometer, if necessary, water with a small amount of mild soap with a solution to wet the cloth. When the use is complete, please cover the infrared thermometer lens cover as soon as possible, and put into the carrying case for storage.
Infrared thermometer ar300 working principle
In nature, all the temperature higher than absolute zero of the object are constantly to the surrounding space to send out infrared radiation energy. The size of the object's infrared radiation energy and its distribution by wavelength? --? With 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.
Infrared thermometer by the optical system, photoelectric detector, signal amplifier and signal processing, display output and other components. Optical system convergence of its field of view of the target infrared radiation energy, the size of the field of view by the thermometer's optical parts and their location to determine. Infrared energy focused on the photodetector and transformed into a corresponding electrical signal. The principle of infrared thermometer blackbody is an idealized radiator, it absorbs all wavelengths of radiant energy, no energy reflection and transmission, the emissivity of its surface is ?1. The signal through the amplifier and signal processing circuitry, and in accordance with the algorithms of the instrument within the therapy and the target emissivity corrected into the temperature value of the target to be measured.
When using infrared radiation thermometer to measure the temperature of the target first to measure the target in its band range of infrared radiation, and then by the thermometer to calculate the temperature of the target to be measured. Single-color pyrometers are proportional to the amount of radiation in the band; two-color pyrometers are proportional to the ratio of the amount of radiation in the two bands.
We can often see is the handheld infrared thermometer, which has a convenient, accurate, safe features, is currently in the medical, equipment troubleshooting is more widely used. Selection of infrared thermometer is should pay attention to performance indicators (such as temperature range, spot size, operating wavelength, measurement accuracy, response time, etc.), ease of use, maintenance and calibration performance and price and other factors. Through the above article we learned that the use of infrared thermometer ar300 is what? What is the principle of infrared thermometer? Then the next time you use it will be more convenient.
