Gas detector DG-7KL3/M for hydrogen, calibration 10/30 %DGW, catalytic sensor, RS-485

Hydrogen Gas Detector Designed for Precise Measurement

The DG-7KL3/M detector is an advanced device for continuous monitoring of hydrogen concentration in various environments—from industrial plants and logistics centers to public utility facilities. It employs proven catalytic sensor technology, ensuring reliable detection and rapid response to potential hazards. This device is particularly suitable for areas where hydrogen leakage or accumulation is a risk.

Design and Communication

The DG-7KL3/M detector is engineered for seamless integration with gas monitoring systems. Communication is established via an RS-485 port using the MODBUS RTU protocol, enabling data transmission to a central control unit and remote device management. The replaceable sensor module simplifies maintenance, calibration, and reduces operational costs—replacing a faulty sensor is quick and straightforward. Additionally, the detector features a built-in LED optical indicator that alerts users when hydrogen concentration exceeds permissible limits.
