Review on 🔥 Highly Sensitive Combustible Gas Detector | Portable Natural Gas Tester Alarm | Propane Methane Gas Sensor | Sniffer with Sound Warning | Adjustable Sensitivity | Flexible Probe by Kenny Sarma

**Caution: At a glance, detailed instructions for use***How to use the device effectively*Overall I am very satisfied with this device. I think this device is reasonably priced given the build quality and the bare bones of the device itself. Bare bones are good because they are such good value for money and anything else would greatly increase their price and for what you bought it for (finding leaks) it will get the job done very efficiently. It looks like you could mount this on a pole or tripod if range is the issue or you know the leak is coming from somewhere but the leak is intermittent. I only received this device today but immediately started using it and putting some tape on the speaker so I can keep this device close to me when I'm working up close. It's probably not waterproof, but if that bothers you and it rains, cover it with a tarp or umbrella. For other reasons, there are more issues than just the gas leak you're trying to find. what the device can do and what you can expect from this device. I thought the black part on the sides was at least a little rubberized, no. To do this, (Quantity 3: AA battery) must be on, the physical sensor is in the red part of the gooseneck. Count to about 20 seconds when the unit is turned on with the front panel switch and the sensor is on to "warm up” the sensor. To set the device: After the sensor has warmed up, the LED on the "Sense indicator" in front will barely light up. block so that no part of the meter gauges is lit (similar to block off). The front speaker volume along with the LED indicators will increase in level and intensity as the concentration in the air increases. You can test your device with any gas source, e.g. a butane source like a cigarette/grill lighter, a natural gas source like a stove, or a propane source (I've posted a picture of the manual with this review). How to Use the Device Effectively After you set up the device and can use it to search for gas leaks, you will soon find that if you place this device in an area with a leak, the device will go haywire. All of this has a learning curve, and it's a small one: just set the sensitivity to whatever level you had when you turned the device on. This effectively "desensitizes" the device so that it will not function if the sensor is exposed to trace gases trapped in the air due to a leak. This is to your advantage because you already know the area of the leak, now you want to pinpoint the exact location of the leak. The lower sensitivity now only works when the sensor is in the leakage current. To practice: Take an outdoor propane grill or lighter, twist it so the gas barely escapes, but don't light the flame. The device will then beep. Reduce the sensitivity of the device to the point where there is either no sound or hardly any sound (depending on need and/or situation). Releasing more gas will now make the device sound more meaningful. HOW TO DETECT A LEAK. This is the part where EVERYONE failed to demonstrate, from hours of googling and watching youtube videos to reviews here. There is one person who made a video in Spanish that either demonstrates this or defies what is possible on YouTube.
