Zhongan S300 gas detector is developed according to national standards and national product quality and technical requirements. The instrument can meet the requirements of sound and light alarm prompt on gas detection site and real-time display and monitoring of gas concentration on site. Infrared remote control type is adopted for field debugging, and parameter setting can be carried out without opening the cover.

Infrared remote control type is adopted for field debugging, and parameter setting can be carried out without opening the cover.
Zhongan S300 gas detector can convert the gas concentration signal leaked in the air into electrical signal remote transmission. The instrument can adopt the output mode of three wire system 4 ~ 20mA or four bus RS485, which has the advantages of long transmission distance and anti-interference.
Zhongan S300 gas detector is widely used to detect the leakage concentration of combustible gas and toxic and harmful gas in industrial environment.
