Description
Overview
GAOTek fixed ammonia gas detector can detect any combustible gas like butane propane acetylene, lpg, natural gas, CNG, the ethanol sensor is with explosion proof shell to collects and detects the gas concentration on the spot, with an optional audible &visual alarm light, when the gas concentration exceed a preset alarm point, the c2h2 detector will make alarm immediately.Â
Features
