Product Description

Product Overview

This fixed real-time monitoring single gas detector with 4-20mA output is specifically designed for hydrogen (H2) gas detection. Hydrogen, being lighter than air and highly flammable, requires precise monitoring of its lower explosion limit and concentration levels in ppm or VOL units.

Key Functions

Continuous monitoring of H2 hydrogen gas in environmental and pipeline applications
Self-calibration and zero calibration functions for enhanced accuracy and reliability
Temperature compensation for precise gas concentration readings across varying temperature conditions
Optional infrared remote control for alarm point settings, zero calibration, and address modification
Optional one or two on-off signal outputs to drive external devices like ventilators or solenoid valves
24V DC operating voltage with durable die-cast aluminum housing
