XAR-UCT is a precise meter that measures UVC radiation. This meter measures UVC light from artificial light sources. It has a 9 inch bendable gooseneck that can locate and detect the UVC light even in hard-to-reach areas. The maximum UVC radiation intensity is always displayed in the use process, which is convenient for users not to contact UVC light. Applications of XAR-UCT include： Monitoring UVC Lamp Intensity & Aging; Testing Eyewear UVC Blocking Capabilities; Measuring UVC Lamp Fixture Leakage; Testing UVC Intensity in Semiconductor Fabrication, and Industrial Process Control etc..
