1. Before wearing protective clothing, make sure to do sufficient inspection work.
Working principle: the use of molecular sieve physical adsorption and desorption technology. The oxygen machine is filled with molecular sieve, nitrogen can be adsorbed in the air when pressurized, and the remaining oxygen that has not been absorbed is collected, and it becomes high purity oxygen after purification treatment.
The optical fiber online long -distance infrared temperature measuring the temperature instrument itself has the characteristics of strong anti -electromagnetic interference ability, corrosion resistance, long transmission distance, and stable work.
The optical system of the distance and the spot, the optical system of the infrared thermometer collects energy from the circular measuring spot and focuses on the detector, the optical resolution is defined as the distance between the infrared thermometer to the object and the ratio of the spotted spot (D) : S).
The filtration efficiency of FFP2 KN95 Masks on particles with aerodynamic diameter≥0.3 m is more than 95%. The aerodynamic diameters of airborne bacterial and fungal spores vary mainly between 0.7 and 10 m, also within the range of protection.（China FFP2 mask)
When the infrared thermometer measures surface temperature, the instrument can receive all three energy. Therefore, all the infrared thermometers must be adjusted to read only the emulated energy. Measurement errors are typically caused by infrared energy reflected by other light sources.
