Gas leak sensor QOLTEC NG 85dB LE – natural gas (CH4) detector, audible alarm 85 dB

QOLTEC NG 85dB LE is a natural gas (CH4) detector designed to identify methane leaks in homes and small commercial spaces. The device continuously monitors ambient air for rising concentrations of natural gas and triggers an 85 dB audible alarm when a hazardous level is detected. The compact unit is intended for use near gas appliances, such as stoves and boilers, and can be wall-mounted or placed at recommended heights for reliable detection of lighter-than-air methane.

Advantages

The detector offers continuous, automatic monitoring without user intervention and provides a clear audible alert at 85 dB to notify occupants of potential methane leaks. Its compact design allows straightforward installation in kitchens, boiler rooms, or utility spaces. The device is suitable for residential and small commercial environments where early warning of natural gas is required.

Key specifications

How to use

Mount the detector on a wall or place it at a recommended height where methane accumulation is most likely to be detected—typically higher than floor level due to methane's lighter-than-air properties. Connect or power the unit according to the manufacturer's instructions and verify operation using any provided test function. Regularly check that the unit is unobstructed and free from dust or debris that could affect sensing performance.

Recommendations

Install the detector near gas appliances but away from direct drafts, windows, doors or ventilation outlets that could disperse gas and affect detection. Test the alarm periodically as described in the user manual and replace the unit or its power source according to the manufacturer's maintenance intervals. In case of alarm activation, evacuate the area, avoid operating electrical switches, shut off the gas supply if safe to do so, and contact emergency services or a qualified technician.
