Description
Overview
GAOTek portable 4 in 1 explosion-proof multi gas detector analyzer is used to quickly detect the occasion of four-in-one gas concentration exceeding the standard alarm. It adopts 2.8 – inch high-definition color screen real-time display, selects imported well-known brand gas sensors, advanced circuit design, mature core algorithm processing, and unique shape design. It can detect the gas concentration in the pipeline or confined space, atmospheric environment, and alarm when it exceeds the standard.
