Gasflag is a single channel control panel manufactured by Crowcon which is suitable for monitoring any 4-20mA flammable, toxic or oxygen gas detector.
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.
Visit hazardous area gas detectors for explosion and flameproof gas monitoring and detection instruments with certification for potentially explosive atmospheres, including Zone 1 and Zone 2 (according to ATEX and IECEx) and Class/Division categories (according to North American standards).
