Hydrogen Bromide (HBr) Gas Detector with High Precision and IP68 Protection – Enviro Testers 

Overview

Enviro Testers hydrogen bromide (hbr) gas detector with high precision and ip68 protection is a cost-effective and intrinsically safe gas detector for the continuous monitoring of toxic gases, oxygen, flammable gases. With IECEx, ATEX certificates, explosion level reaches Ex db IIC T6 GB/Ex db ia IIC T6 GB/Ex da db ia IIC T6 GB. Having a 3-wire 4 to 20 mA analog output with relays, it also offers HART, RS485 Modbus protocol, making it compatible with most control systems. With optional wireless function, no need wires to save the labor cost and realize the transmission without limits. Adopt magnetic wand design, it’s safe and easy to do menu navigation in explosion areas. It is also an intelligent hot swappable fixed gas detector, which is easy for maintenance after installation.

 

Features
