The consequences and cleaning methods of lens contamination in monochromatic infrared thermometers
1. Gently blow away the floating dust. If there is a lot of dust, it can be slowly blown away with compressed air, etc.
2. Gently wipe off any remaining particles with a soft brush or specialized lens paper.
3. Dip a cotton swab or lens paper in distilled water, wipe the surface of the lens, and be careful not to leave scratches. For handprints or other oils, the following cleaning methods can be used:
Kodak lens swab
Ethanol
Industrial alcohol
Wipe the edge of the infrared thermometer lens with an alcohol swab
Wipe the objective lens of the infrared thermometer with lens paper
When cleaning the lens, appropriate methods should be selected according to the needs and actual situation, and attention should be paid to light movements. A soft and clean cloth should be used until the surface color of the lens is visible, and then it should be dried in the air. Be careful not to dry the surface of the lens to avoid leaving scratches. If there is a coating layer on the lens, it can be wiped with ethane and then air dried.
There is some contamination on the lens of the infrared thermometer, which does not affect the accuracy of the dual color infrared thermometer, but has a significant impact on the monochrome infrared thermometer. Of course, if the lens is too dirty and the sensing head cannot obtain sufficient infrared energy, even with a dual color infrared thermometer, the measured temperature value will have a significant deviation. Therefore, in daily maintenance and use, attention should be paid to keeping the lens clean to ensure the normal operation of the thermometer and meet the measurement needs.
