The Ermenrich NG20 gas detector is a portable gas detector that detects gas leaks with immediate response and intuitive operation. It should always be at hand if there are gas appliances in the house, such as a stove, water heater, fireplace, boiler, etc. It prevents fires by drawing attention to the source of danger in time. It is recommended to check the gas appliances at home, including the pipes, at least once a week.

Instead of a screen, the device has a small panel with alarm indicators - a yellow LED lights up at 500 ppm (low leakage) and a red LED lights up at 2000 ppm (high leakage). It also beeps. If the green LED is on, the gas concentration is normal. If the green LED is flashing, the batteries should be replaced immediately.

The device is light, fits comfortably in the hand and runs on two standard batteries. Thanks to the automatic switch-off function, it saves energy. One set of batteries is sufficient for an average of 200 measurements.
