LPG LNG Methane Propane Butane Gas Leak Detector with LCD Alarm
Advanced detector designed to identify leaks of combustible gases such as LPG, LNG, methane, propane, and butane. Equipped with a high-sensitivity semiconductor sensor, approximately 85 dB audible alarm, LED visual indicators, and an LCD display showing gas concentration levels. Suitable for kitchens, boiler rooms, garages, laboratories, and areas with gas-powered equipment. Operates on mains power with 9V backup battery for continuous safety monitoring.
Combustible Gas Leak Detector LPG / LNG / Methane / Propane / Butane with Audible and Visual Alarm
Application
The detector is designed for installation in residential, commercial, and light industrial environments where the risk of combustible gas leakage exists. It is commonly used in kitchens with gas stoves, boiler rooms with natural gas or propane-butane heating systems, and in rooms containing gas cylinders, gas meters, tanks, or gas pipelines.
The device can also be installed in garages for vehicles equipped with LPG systems, school chemistry and physics laboratories, as well as in vehicles, caravans, boats, and motor yachts.
Detected gases
Natural gas (LNG), methane, propane, butane, and propane-butane mixtures (LPG).
Sensor type
High-reliability semiconductor sensor designed for rapid detection of combustible gases and immediate response to increased gas concentration in the environment.
Main features
- Audible alarm and visual LED warning
- Voice notifications indicating device status and alarm conditions
- LCD display showing real-time gas concentration levels
- Automatic sensor fault detection
- Alarm memory function
- Dual power supply: mains power with battery backup
- Continuous gas concentration monitoring
- High-sensitivity semiconductor gas sensor
Installation
The detector should be installed in the same room as the gas appliance or close to a potential leakage source. The recommended maximum distance from a possible gas leak source is up to 3 meters.
- Natural gas / Methane / LNG: Install on the wall 30–100 cm below the ceiling
- LPG / Propane / Butane: Install on the wall 30–100 cm above floor level
- Maximum distance from potential gas leak source: up to 3 m
Main device components
- AC power connection
- LCD display indicating gas concentration
- Gas inlet openings directing gas toward the sensor
- Alarm siren speaker
- Status indicator LEDs
- Test button for checking audible and visual alarm signals
LED indicators
- Green LED: Device operating normally, no gas detected
- Yellow LED: Flashing indicates malfunction or sensor fault
- Red LED: Flashing indicates detection of dangerous gas concentration
The device can also operate with a 9V backup battery. When the battery level becomes low, the detector provides a warning signal indicating that the battery needs replacement.
