Introduction
The UVC band is short-wave sterilized ultraviolet light, with a wavelength of 200nm~280nm, which has a strong bactericidal effect, which can destroy the molecular structure of DNA and RNA in bacteria and viruses, and cause growth cell death and regenerative cell death. Ultraviolet disinfection and sterilization is widely used, used in the Center for Disease Control and Prevention, pharmaceutical factories, food factories, schools, nurseries, cinemas, buses, offices, homes, etc., it can purify the air and avoid the spread of germs through the air or through the surface of objects.
The UVC probe is one of the 9 probes of the LS125 ultraviolet irradiance meter, with a response wavelength of 230nm-280nm, which is a digital probe that specializes in detecting the intensity and energy of UVC 253.7nm high-power germicidal lamp.

1. Large range measurement, the maximum power can be measured to 200000μW/cm2.
2. The instrument can measure both energy value and power value at the same time.
3. With rich statistical functions, real-time power value, maximum value, minimum value, average value, measurement time, and energy value are displayed at the same time.
4. It can switch between 3 measurement units, namely μW/cm2, mW/cm2, W/m2, and the data conversion between different units does not need to be manually calculated.
LS125 multi-probe ultraviolet irradiance meter, using digital probe, plug-in design, one host can match a variety of probes, the instrument intelligently judges the model of the probe, according to the test of ultraviolet spectrum range, range, size of the measuring hole, application industry, etc., 9 different ultraviolet probes have been developed, each probe selection refers to the following figure:
