LS125 UV Light Meter+UVC LED Probe

LS125 UV Light Meter+UVC LED Probe


     Ⅰ.Brief Introduction 

      UVC light source can be divided into two kinds, the first one is the traditional low-pressure mercury germicidal lamp, and another one is UVC LED germicidal lamp. Compared with low-pressure mercury lamp, LED lamp has longer service life and higher efficiency, more energy-saving. Because the spectral curves of low-mercury germicidal lamps are not the same as the spectral curves of LED germicidal lamps, the probes used in the tests are not the same.
