Description
Overview
GAO Tek Portable multi gas detector an intelligent high-performance detection alarm that can continuously detect and monitor volatile organic compounds VOC, TVOC, combustible gases, toxic and harmful gases and with function of people falling alarm. The detector adopts more than 30 kinds of smart sensors, including imported PID optical sensor, electrochemical sensor, oxygen, catalytic combustion sensor and infrared flammable sensor, CO2 sensor, CH4 sensor, which can detect 4 kinds of toxic at the same time.
