Product Overview

I recently had the opportunity to try out the TOPTES PT177 Gas Leak Detector and I must say that it exceeded my expectations. This device is essential for any household that has gas appliances, making it easy to quickly and accurately pinpoint any gas leaks. I found it incredibly simple to use, and I was pleased with how precise the results were.

The TOPTES PT177 is a small, pocket sized device with a handy pocket clip so you can keep it on you at all times. It comes with two AAA batteries, which you simply need to load into the device before using it. After that, a 30 second automatic calibration process takes place and then you re ready to go. All you have to do is point the device near where you suspect the leak to be holding it a couple of centimeters away and it will almost immediately detect any gasses present and alert you via five bright red LEDs visual and an audible 75dB alarm that increases in volume as the concentration of gas increases.

The detector has some additional user friendly features too, such as a power indicator light that flashes when the battery voltage is below 2.4V, reminding you to replace the battery in time. Furthermore, if inactive for 5 minutes without operation or detecting gas, PT177 will automatically turn off saving energy and conserving battery life.

In terms of accuracy and detection range, this device really impressed me. The Leak Detector can detect combustible gasses including LPG, methane, ethane, propane, butane, natural gas, coal gas, gas fuel and liquefied natural gas with a detection range of 50 1000ppm based on Methane.

In conclusion, I would highly recommend the TOPTES PT177 Gas Leak Detector for anyone who has gas appliances in their home or workplace. It s incredibly easy to use and provides accurate results making it an essential safety tool for regular checks around your home or business premises. Furthermore, TOPTES provide excellent after sale service with a 3 year warranty and lifetime technical support so if there are ever any issues or questions then they are always on hand to help out!
