Macurco GD-12 Propane (LP) Methane (NG) Hydrogen (H2) Fixed Gas Detector, 100-240VAC, Grey

Protect people, property and operations with the Macurco GD-12 fixed gas detector — a commercial-grade gas leak sensor designed for dependable propane (LP), methane (NG) and hydrogen (H2) monitoring. The GD-12 combines catalytic sensing technology with line-voltage convenience (100-240VAC) and a 4-20mA current loop to integrate easily into security, surveillance and building management systems. Built-in 5A fan and 0.5A alarm relays automate ventilation and alert procedures, helping to reduce combustible gas concentrations before they become hazardous. A clear digital display (0–50% LEL) and internal buzzer simplify on-site diagnostics, while UL 61010-1 listing ensures trusted performance in commercial environments. Compact and versatile, the GD-12 mounts in ducts, on walls or surfaces and covers roughly 900 sq. ft., making it a practical choice for parking garages, battery charging stations, mechanical rooms and loading docks. Backed by a two-year limited warranty, the Macurco GD-12 delivers reliable gas monitoring that integrates with your security and facility monitoring strategy.
