Portable Combustible Gas Detector – Audible & Visual Alarm
Portable Combustible Gas Detector – Audible & Visual Alarm
Stay Safe with the VODOOL Portable Combustible Gas Detector
Keep your home, kitchen, RV, or workplace secure with this compact and reliable combustible gas detector. Featuring both audible and visual alarms, this handheld gas sniffer detects dangerous concentrations of natural gas, LPG, methane, propane, ethane, carbon monoxide, and more — giving you fast, clear alerts so you can act quickly.
Key Features
- Fast Alarm Response: Detects combustible gases and triggers audio-visual alerts within 2–5 seconds. As gas concentration rises, alarm intensity increases, keeping you fully informed.
- Wide Gas Detection: Identifies natural gas, LPG, methane (CH₄), ethane (C₂H₆), propane (C₃H₈), ethylene (C₂H₄), propylene (C₃H₆), acetylene (C₂H₂), carbon monoxide (CO), and more.
- Semiconductor Sensor: High-sensitivity semiconductor sensor with a warm-up time of approximately 30 seconds and a detection range of 50–1000 ppm (methane). Response sensitivity is under 50 ppm.
- Analog Display + Sound Alarm: Concentration indicator bars increase in number and frequency as gas levels rise, providing a clear visual readout alongside the audible alert.
- Compact & Lightweight: Slim ABS housing measuring approx. 145 × 35 × 20 mm makes it easy to carry during routine inspections, emergency checks, or travel in your RV.
- Battery Powered: Runs on 2 AAA alkaline batteries (not included) — no charging required, ready whenever you need it.
- Versatile Use: Ideal for homes, kitchens, RVs, power plants, chemical facilities, LPG stations, underground pipelines, and more.

How to Use
- Press the power button in a clean-air environment to turn on the device.
- Allow approximately 30 seconds for preheating. A "beep" sound and flashing indicator confirm the device is ready.
- Move the sensor head close to areas where gas leaks may occur.
- Watch the concentration indicator bars — more bars and faster flashing indicate higher gas concentration. The audible alarm will intensify accordingly.
- Press the power button again to turn off after use.

Frequently Asked Questions
Q: What types of gases can this combustible gas detector detect?
A: This portable gas detector is capable of identifying a wide range of combustible gases including natural gas, LPG, methane (CH₄), ethane (C₂H₆), propane (C₃H₈), ethylene (C₂H₄), propylene (C₃H₆), acetylene (C₂H₂), propyne (C₃H₄), and carbon monoxide (CO), making it suitable for home kitchens, RVs, chemical facilities, and more.
Q: How quickly does the gas leak detector trigger an alarm?
A: The detector responds within 5 seconds for concentrations at or below 500 ppm, and within just 2 seconds for concentrations above 500 ppm. Both an audible beep and visual indicator bars activate simultaneously, with alarm intensity increasing as gas concentration rises.
Q: Does the combustible gas detector require charging or special batteries?
A: No charging is needed. The detector is powered by 2 standard AAA alkaline batteries (not included), making it fully portable and ready to use anywhere — at home, on the road in your RV, or at a worksite.
Q: Do I need to wait before using the gas detector after turning it on?
A: Yes, a short warm-up period of approximately 30 seconds is required after powering on. During this time, the gas sensor and indicator light will flash. A "beep" sound confirms the device is fully preheated and ready for accurate detection.
