IECEX ATEX Certified CH4 Gas Detector with IP66/68 Protection and Wireless LORA/4G Option for Methane Leak Detection
High-precision Fixed CH4 Gas Detector with diffusion detection principle, designed for industrial safety applications.
SG100 series is a cost-effective and intrinsically safe gas detector for the continuous monitoring of toxic gases, oxygen, and flammable gases. With IECEx and ATEX certificates, explosion level reaches Ex db IIC T6 GB/Ex db ia IIC T6 GB/Ex da db ia IIC T6 GB. Featuring a 3-wire 4 to 20 mA analog output with relays, it also offers HART and RS485 Modbus protocol, making it compatible with most control systems. Optional wireless function eliminates wiring needs, saving labor costs and enabling transmission without limits. Magnetic wand design ensures safe and easy menu navigation in explosion areas. This intelligent hot-swappable fixed gas detector simplifies maintenance after installation.
