## Features

- Effective Gas Leak Detector: TOPTES PT520A natural gas detector can accurately help you locate the gas leakage of various combustible gases in tight spaces, such as methane, natural gas, propane, LPG, gasoline, etc. Note: Please allow 30 seconds of warm-up time before the operation
- Flexible Probe Easy to Use: With a 17-inch flexible gooseneck (bendable in any direction), the portable gas leak detector makes it easy for you to access hard-to-reach areas, such as natural gas pipelines, propane storage tanks, gas fireplaces, sewers, basement, RV, and other narrow space. It can be carried anywhere to find leaks no matter outdoors or indoors
- Visual and Audible Alarm: PT520A will rapidly respond in 0.5 seconds while gas is detected. Seven colored analog bars and a 75dB audible buzzer help you point out the gas leak location. Both of them increase with combustible gas concentration. Detection range: 50 to 10,000 ppm (based on Methane)
- User-Friendly Functions: Activate or cancel the Auto Power-Off function through the APO button just in your need. When canceled, the detector will turn off after 10 minutes of inactivity to save power. In addition, you can turn off the audible alarm at any time via the Mute button to eliminate annoying alarm noise. The double-sided bar-shaped groove design and non-slip material make it wear-resistant and easy to hold

## Questions & Answers

**Q: Can this product detect nitrogen?**
A: Thank you for your inquiry. We appreciate your interest in our PT520 series products.

Nitrogen is a nonflammable gas in air, and as such, the PT520 series products are primarily designed to detect combustible gases. Regrettably, the PT520 series is unable to detect nitrogen at this time. We apologize for any inconvenience this may cause in meeting your current needs.

However, we are continuously working to expand our product range to cater to a wider range of requirements. In the near future, TOPTES is planning to launch its very own nitrogen detector. We encourage you to stay updated with the latest news from TOPTES, as we are dedicated to delivering innovative solutions to meet our customers' evolving demands.

If you have any further questions or need assistance with any other products, please don't hesitate to contact us. We value your interest and hope to be able to fulfill your requirements in the future.

**Q: Can this product detect sewer gas(methane/hydrogen sulphide)?**
A: Hi, TopTes PT520A Combustible gas detector could detect methane, but not Hydrogen sulfide.
The main component of sewer gas is methane, although it can also contain other gases such as carbon dioxide (CO2), hydrogen sulfide (H2S), and ammonia (NH3). 
TopTes PT520A gas leak detector could detect most combustible gases like methane. 
Thus, for methane, PT520A could but for hydrogen sulfide, it couldn't

## Customer Reviews

### ⭐⭐⭐⭐⭐ Ideal safety kit in fact a must particularly for caravaners
*by P***L on 13 September 2025*

Superb piece of kit. Easy to use. Instant result both audio and visual. My leak ( a faulty Calor bottle valve) was found instantly. Entire gas line was checked with the greatest of ease. I now check each cylinder as it is purchased.

### ⭐⭐⭐⭐⭐ Gas detector
*by I***H on 4 March 2024*

This is a lot better than I expected. It feels robust, the goose neck holds its shape well and is a good length. It is easy to use, the only special action you need to do is to 'zero' it when you turn it on. You do this by turning it on somewhere with no combustible gases (I step outside to do this) and just wait about 15 seconds.Test it out by, for example, turning on a gas ring on your job briefly or letting gas escape from a lighter. I found my white board pen with the cap off was enough to set it off.Other came comments mention that the display is not bright enough. It is not backlit, so if you plan to use it outdoors you may need to cup your hand around the display to see it better, depending on the ambient light. This is not a problem for occasional outdoor use ( I checked my gas meter) but might annoy if you plan to use it primarily outdoors. There was no problem at all using it indoors - the display was very clear.It confirmed I don't have a gas leak, so was worth the money for me.Unless you will be using it regularly I would recommend removing the batteries while it is being stored, just in case they leak. It came with 3 AAA Duracell batteries and I have had that brand leak in the past. (I generally prefer Energizer for this reason). You unscrew the battery compartment with a small Philips screwdriver.The instructions, I would guess, have been translated into English from another language and this had been done quite well. There is no difficulty understanding them and I found some of the phrasing quite amusing (though this could just be my weird brain).

### ⭐⭐⭐⭐ It’s a gas gas gas.
*by C***K on 18 May 2023*

It works. I did an LPG gas connection, it didn’t detect gas…. Good joint…. Checked it on a tiny on purpose leak tested with bubble. It works. Easy to use . Handy telescopic sensor for poking around looking for leaks.Yes. Quite good.
