ABUS GWM100ME Natural Gas Detector – Methane Alarm, 85 dB Siren, Relay Output, 230V Wall-Mount

Triggering at just 10% LEL, the ABUS GWM100ME provides an early warning against methane leaks before they become explosive. This wall-mounted natural gas detector runs directly on 230 V AC, so there are no batteries to replace – just continuous protection for your home or small business.

Overview

The ABUS GWM100ME is a dedicated natural gas (methane, CH4) detector built to safeguard homes and small commercial spaces from the dangers of gas leaks. Using a semiconductor sensing element, it continuously monitors the air and triggers an alarm when gas concentrations reach a critical 10% LEL threshold – well before hazards escalate. The sensor is powered directly by standard 230 V AC mains and requires no battery replacement, making it a low-maintenance safety solution. Its compact white ABS housing blends discreetly into any wall while providing the electronics robust protection against everyday environmental factors.
