Gas leak sensor QOLTEC Certified Propane-Butane (LPG) detector with 85 dB alarm and LED indicators

QOLTEC certified propane-butane (LPG) gas leak sensor is a compact indoor detector designed to continuously monitor the air for the presence of flammable LPG and warn occupants with both audible and visual signals. The device detects propane and butane concentrations and triggers an 85 dB alarm and LED indicators when gas levels exceed the sensor threshold. Intended for placement near household or small commercial appliances, tanks and supply lines, this unit supports timely response to reduce the risk of fire or explosion.

Advantages

The detector combines an audible 85 dB alarm with multicolour LED indicators to provide clear and immediate notification of detected LPG. Its compact form factor allows installation close to potential leak sources without occupying much space. Continuous active monitoring ensures the sensor is ready at all times, while simple visual cues make it easy to interpret status at a glance. The design focuses on basic, reliable gas detection for indoor environments.

Suitable for

• Homes with LPG-powered stoves, heaters or boilers
• Small commercial kitchens and catering areas using propane or butane
• Storage areas and utility rooms with LPG cylinders or supply lines
• Workshops and service rooms where portable LPG appliances are used

Key specifications

• Gas type detected: propane and butane (LPG)
• Alarm output: 85 dB audible alarm
• Visual indicators: LED status lights for power and alarm
• Operating environment: indoor use near appliances, tanks or supply lines
• Form factor: compact wall- or surface-mounted housing

How to use

Install the sensor on a wall or another vertical surface near the potential leak source, following the manufacturer’s recommended mounting height and orientation for LPG detection. Connect power or insert batteries as required, verify the power LED is on, and allow the sensor to stabilise. Periodically test the alarm using the test function, and respond immediately to any alarm by ventilating the space, shutting off LPG supply if safe to do so, and evacuating the area until the source is addressed.

Usage recommendations

Place the detector at the correct height according to the gas behaviour (consult the device manual), avoid mounting directly above stoves where cooking fumes may cause false alerts, perform regular tests of the alarm, and replace the unit or its batteries according to the manufacturer’s maintenance schedule to ensure reliable operation.
