Wall-Mounted Single H2S Gas Detector With 4-20mA/ RS485 Signal Output
Product overview
The SG100 gas detector is an intelligent hot swappable fixed gas detector that is easy to maintain after installation and can continuously monitor toxic gases, oxygen, and combustible gases. Through IECEx and ATEX certification, the explosion-proof level reaches Ex db IIC t6gb/Ex db IIC t6gb/Ex da db IIC t6gb. Equipped with a 3-wire 4 to 20 mA analog output relay, it also offers HART, RS485 Modbus protocols, making it compatible with most control systems. Adopting a magnetic rod design for easy menu navigation in explosive areas.
