Description
Overview
GAOTek Portable HCL Gas Detector adopts imported high performance sensor, is 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. Harmful gases can be flexibly configured in any combination to meet the analytical testing needs of different industries. It is built-in temperature and humidity sensors, display temperature and humidity real-time. gas detector wireless function allows the security personnel can get a real-time equipment data and alarm status in any place. Visual data displays, large 2.3 inch full-colour screen and quicker response time help improve personnel safety and protection to a whole new level.
