Description
Overview
GAOTek Portable Multi Gas Detector uses imported high-performance CO H2S O2 and CH4 sensors, which is an intelligent high-performance detection alarm that can continuously detect and monitor CO H2S O2 and CH4 gas with the function of people falling alarm. It has built-in temperature and humidity sensors, displaying temperature and humidity in real time. GASTiger2000 wireless function allows the security personnel to get real-time equipment data and alarm status in any place. Visual data displays, a large 2.3-inch full-color screen and quicker response time help improve personnel safety and protection to a whole new level.
