Flammable gas leak detector – LPG, natural gas, methane, propane
A modern flammable gas detector is a reliable tool for quickly detecting leaks in installations and warning about dangerous concentrations of selected substances. The device features simple operation, high sensitivity, and multiple conveniences, making it suitable both for home and industrial use.

Package contents:

• GM8800B gas detector

• 4 × 1.5V AA batteries

• Original manufacturer’s packaging

• Instruction manual in Polish

Technical specifications:

• Detection range: from 50 ppm (methane)

• Sensor: semiconductor, low power consumption

• Warm-up time: ≤ 60 s

• Response time: ≤ 2 s

• Power supply: 4 × 1.5 V AA (up to 8 h continuous use)

• Operating temperature: 0 – 50 °C

• Housing dimensions: 177 × 68 × 46 mm

• Probe length: 38.5 cm

• Weight (without batteries): approx. 300 g

Applications:

• Home and apartment – quick inspection of gas stoves, heaters, CO boilers.

• Services and workshops – LPG/CNG system diagnostics, fuel line leak detection.

• Industry – monitoring of petrochemical plants, wastewater treatment plants, water purification stations.

• Research laboratories – observation of chemical processes requiring control of volatile compound leaks.

Why is it worth it?

• Instant signaling – LED indicator and sound alert notify of gas presence within 2 s of detection.

• Adjustable sensitivity and auto-calibration – easily set the detection threshold, while the built-in system automatically calibrates the sensor at startup.

• Flexible 40 cm probe – allows access to hard-to-reach places in boiler rooms, near meters, or gas cabinets.

• Mini-jack socket – enables headphone connection for work in noisy environments or discreet testing in residential areas.

• Universal use – inspection of stoves and water heaters, LPG/CNG systems, production lines in chemical and agricultural industries, HVAC service, car workshops.

Detected gases (examples):

• natural gas (CH₄)

• propane, butane, LPG

• ethane, propanol, ethanol

• gasoline vapors, kerosene, solvents

• ammonia, hydrogen sulfide, carbon monoxide*

• water vapor or smoke may cause a temporary signal (interpret readings with caution)
  *The detector reacts to CO but does not replace a dedicated carbon monoxide detector.

Safety first
Regularly check gas installations – even a small leak can lead to explosive mixtures. A gas detector is the first line of defense against uncontrolled ignition and poisoning.
