    • Easy to Use and Detects Gas Quickly
Size: PT205 with %LEL Value Color: Orange
This gas detector is simple to use right out of the box. It powers on quickly, and the sensor starts detecting gas leaks within seconds. The display is clear, and the readings update in real-time, making it easy to pinpoint leaks. The detection is sensitive, so it picks up even small traces of gas. It’s a helpful tool for checking around stoves, gas lines, and propane tanks. What I Like: • Fast detection – The sensor responds quickly, making it easy to locate leaks. • Clear display – The screen shows gas levels in a way that’s easy to understand. • Simple operation – Just turn it on and start scanning without complicated setup. ... show more

Serves its purpose. I bought this primarily to test the gas whenever I change cylinders...still using changeable 50lbs cylinders of propane so it's nice to test after each change to verify its leak free.

this device works really well, and it being compact, I can put it on my ballistic vest and walk around without issue. The device is small, yet the sensors work really well. It is easy to use and the instructions are designed for individuals who do not have technical knowledge of gas sensors. Works very well. ... show more

    • Inexpensive and effective!
Size: PT199 Gas Leak Detector Color: Orange
What a great tool! Had a tiny gas leak that I could not locate with the spray soap method. You would think the gas would accumulate over time but it never got strong to cause much concern that there was a real issue (but of course there was). Gave up trying and bought this tool. Took all of 5 minutes to locate the issue on the main pipe fitting coming into the house. Very happy I got this tool and would recommend it to everyone who suspects and leaks. ... show more
