Domestic gas detectors

Domestic gas detectors H-400-CH4 is intended to monitor concentration of methane and signal light and sound at excess levels.

LED: green LED – normal operation, red – alarm, yellow – failure

The first time sensor heats 30s. Device gives a double beep sound and lights green LED /normal operation/.

Upon reaching levels above 20% LEL methane red LED lights, the unit emits a continuous beep. After 5 seconds, the relay output is activated, which stops the gas supply.
Gas detector allows calibration with standard gas. H-400-CH4 meets the requirements of EN 50194.
