The infrared thermometer waveform generator can connect up to 16 waveforms for long or very complex waveforms to form a waveform sequence. Each waveform can have 1 to 32468 repetitive or cyclic numbers defined by the user.

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.

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 ......
