SG100 Transmitter

The SG100 Series is a cost-effective and intrinsically safe gas detector designed for continuous monitoring of over 50 toxic and oxygen gases in the most challenging environments.

Certified by IECEx, ATEX, and CNEX, its explosion-proof rating reaches Ex db IIC T6 GB/Ex db ia IIC T6 GB/Ex da db ia IIC T6 GB. Featuring a 3-wire 4–20 mA analog output with relays, as well as HART and RS485 Modbus protocols, it is fully compatible with most control systems. With an optional wireless function, the SG100 reduces wiring requirements, lowers labour costs, and enables limitless transmission.

A three-key magnetic wand design makes menu navigation safe and simple in explosive areas, while hot-swappable sensors ensure easy maintenance after installation. Additional features such as remote calibration, self-diagnostics, and latched alarms make the SG100 a versatile and reliable choice for gas detection in petroleum, chemical, metallurgy, power, and other industrial applications.
