Description
Overview
GAOTek portable dust detector is made by the principle of laser scattering and the use of pumping and sampling. It mainly tests the particulate matter suspended in the air, and the data output is the concentration weight mode.This instrument adopts the advanced microcomputer technology, which is processed by the central processing unit, which has the advantages of fast processing speed, strong anti-interference ability and high measurement accuracy.
