Gas Detection Control Panels

Crowcon Gasflag

Gasflag is a single channel control panel manufactured by Crowcon which is suitable for monitoring any 4-20mA flammable, toxic or oxygen gas detector.

The Gasflag is ideally suited to light industrial or commercial applications such as LPG monitoring on garage forecourts, chlorine detection in swimming pool dosing rooms, or methane detection in boiler rooms.

Crowcon Gasflag control systems feature a loud sounder, bright LED indicators and relays for switching external devices such as audible visual alarms or valves and they provide a clear indication of gas hazards.
