The Ermenrich NG20 gas sensor is a portable gas sensor with instant response and intuitive operation for detecting gas leaks. 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 the outbreak of fires by indicating the source of danger in time. It is recommended to check the gas appliances in the house, including the pipes, at least once a week.

Instead of a display, the device has a small control panel with alarm displays - a yellow LED lights up at 500 ppm (low leakage) and a red LED lights up at 2000 ppm (high leakage). There is also an audible alarm, when the green LED lights up, the gas concentrations are normal. When the green LED flashes, the batteries should be replaced immediately.

The unit is lightweight, easy to hold and operates with two standard batteries, while an automatic shut-off function saves battery power. One set of batteries is sufficient for an average of 200 measurements.
