Overview
Specifications
Application
U-10/20 is a pocket UV radiometer with many advantages including high accuracy, wide test range, compact size, low power consumption, stable performance, easy operation and portability. It adopts S serials linear UV detector to obtain compact size, good stability and low effect from visible light (the visible light can be filtered furthest). It is widely applied to the UV radiation measurement in sterilization, photoetching, water disposal, medical treatment, breeding and UV index evaluation etc.
