Combustible Gas Leak Detector

This is suitable for LPG, methane, ethane, propane, butane, natural gas, coal gas, gas fuel, liquefied natural gas, etc., and it will exactly pinpoint a leak, reducing the risk of gas explosion and keeping your family and property safe.

Visual & Audio Gas Alarm

The gas detector employs both visual alarm and audible alarm as fast as 0.5 seconds of detection. When the bar graph increases and the detector beeps, you know gas has been detected. The alarm increases with the amount of gas, and the LCD screen will turn red when the gas concentration is high.

Batteries Included & Easy to Use

The comes with 2x AAA Alkaline Batteries, so you will be able to set the detector up and have it ready as soon as you receive it. The system warm-up time is about 30 seconds. The low battery indicator will engage when battery voltage is below 2.4V. Automatic power off after 5 minutes without operation or gas detection.

Compact Design

Pocket-sized with a pen hook that allows you to carry it in your shirt pocket. The non-slip texture and material make it easy to hold. With included storage bag, the natural gas detector is also easy to store. It is a great tool for RV-ers, DIY-ers, homeowners with gas appliances, and so on. Saves you from paying hundreds of dollars in diagnostics or wasting gas in an undetected leak.

Products Size：

Without LCD：158*28mm

 

FAQ
Q: How to set up the detector to make it ready to detect?
A: Turn on and wait for 30 seconds to warm up. Please keep in mind that the warm-up process should be performed in a known 'clean' environment to achieve accurate results.
Q: How can I tell what sensitivity the detector is currently at?
A: When the S button light is on, the detector is in high sensitivity mode; when the S button light is off, the detector is in low sensitivity mode.
Q: Does the alarm continue until the situation is resolved?
A: Yes, the alarm will continue to sound until the combustible gas concentration is below 5% of the lower explosive limit.
Q: How close does the detector need to be to detect leaking gas from a natural gas pipeline?
A: Generally 1-5cm, depending on the severity and concentration of the gas leak.
Q: Can the sensors be replaced?
A: We do not sell sensors separately. If you find that the sensor is no longer working within three years from the date of purchase, please get in touch with us.
Q: What is the difference between a gas monitor and a gas leak detector?
A: Gas monitors are used for continuous gas leak monitoring to monitor the air state in a large space, but they are unable to pinpoint the exact leak point. The gas leak detector is used to locate the source of the gas leak.
Q: Why doesn't the screen light up/can’t be turned on?
A: The first thing to check is whether the battery is installed correctly (make sure the electrodes are oriented correctly). Next, please check whether the battery voltage is sufficient, and replace two new batteries to see if the detector works properly. If the problem persists, please get in touch with us to apply for exchange service.
