Description
Overview
GAOTek ammonia gas detector for oil wells is a fixed gas detector installed in a place where potential gas hazard exists to measure oxygen, toxic gas and combustible gas. With ATEX approval, it is suitable for explosive environment use. It communicates with the control panel through 4 to 20 mA analog output or RS485 digital signal.
Features
