Fixed Gas Detector

الوصف

BS*3 fixed gas detector, adopting high-quality gas sensor and SMD arts & crafts, has advantages of good reproducibility, disturb-proof against temperature and humidity, long life-span and easy operation, so it is suitable for gas detection for industrial use. It can transfer the gas concentration in the air into digital signal output. It adopts output of ***0mA three-line electric current signal, which has advantages of long-distance transmit and good disturb-proof. It is suitable for gas detection in refineries, chemical plant, LPG station, gas boiler, and Spray-Paints etc. where gas leakage occurs easily.
