Infrared thermometer knowledge analysis
Infrared thermometers are easy to use and use infrared technology to quickly and easily measure the surface temperature of an object. Temperature readings are taken quickly without mechanical contact with the object being measured. Simply aim, press the trigger and read out the temperature data on the LCD display. Infrared Thermometers are lightweight, small, easy to use, and reliably measure hot, hazardous, or hard-to-reach objects without contaminating or damaging the object being measured. Infrared thermometers can take several readings per second, whereas contact thermometers take several minutes per second to measure. It receives invisible infrared energy emitted by a wide range of objects themselves. Infrared radiation is part of the electromagnetic spectrum, which includes radio microwaves, ultraviolet, radio waves, visible light, R-rays and X-rays. Infrared is located between visible light and radio waves, infrared wavelengths are often expressed in microns, with a wavelength range of 0.7 microns - 1000 microns, in fact, the 0.7 microns - 14 microns band is used for infrared thermometers.
Infrared thermometer Application areas are very wide, mainly in the following areas:
1, food field: scanning management, service and storage temperature.
2, the electrical field: check faulty transformers, electrical panels and connectors.
3, the automotive industry: diagnosis of cylinder and heating / cooling system.
4, HVAC field: monitoring air stratification, supply / return records, furnace performance.
5, other areas: many engineering, base and transformation applications and other areas are in use.
Infrared thermometer use of things to note:
The use of infrared thermometer to measure the temperature, the infrared line pyrometer to the object to be measured, press the trigger in the instrument LCD read out the temperature data, to ensure that the arrangement of the distance and the ratio of spot size and field of view.
Infrared thermometer when, be sure to pay attention to the following precautions:
1, can only measure the surface temperature of the object, can not measure its internal temperature.
2, infrared thermometer can not measure the temperature through the glass, glass has a very special reflection and transmission characteristics, does not allow infrared temperature readings. But can be measured through the infrared window temperature. Infrared thermometer is best not used for temperature measurement of bright or polished metal surfaces (stainless steel, aluminium, etc.).
3, to carefully locate the hot spot, found the hot spot, infrared temperature measurement instrument to aim at the target, and then on the target for up and down scanning movement, until the hot spot is determined.
4, the use of infrared thermometer, pay attention to environmental conditions: smoke, steam, dust, etc.. They will block the instrument's optical system and affect the temperature measurement.
5, the use of infrared line pyrometer, but also pay attention to the ambient temperature, infrared thermometer knowledge analysis if the infrared thermometer is suddenly exposed to the ambient temperature difference of 20 degrees or higher, allowing the instrument to be adjusted to the new ambient temperature within 20 minutes.
