Review: TopTes PT520A Gas Detector - I recently purchased the TopTes PT520A Gas Detector for added safety in my home and RV, and I am very impressed with its performance.

The 43.5cm gooseneck is flexible yet sturdy, allowing me to reach into tight spaces and awkward angles effortlessly. It’s lightweight and portable, making it convenient to carry around the house or in the RV. Setting up the detector was straightforward. It came with three batteries included, so I was able to use it right out of the box. The device powers on quickly, and the user interface is intuitive. The on/off button, combined with sensitivity adjustment, is simple to operate, even for someone who’s not particularly tech-savvy. The TopTes PT520A does an excellent job at detecting gas leaks.

The audible alarm is loud and clear, which gives peace of mind knowing I won’t miss a detection alert.

It’s reliable, easy to use, and provides an extra layer of safety for both my home and RV. It’s well worth the investment for anyone looking to protect their property from potential gas leaks. Review: Gas detector - 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). ## 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 - What You Get: 1×PT520A Gas Leak Detector, 3×AAA Batteries, 1×Protective Case, and 1×User Manual ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BTM3G8DK | | Alarm | Audible, Visual | | Best Sellers Rank | 14,042 in DIY & Tools ( See Top 100 in DIY & Tools ) 8 in Gas Detectors | | Brand | TOPTES | | Colour | Orange | | Country of Origin | China | | Customer Reviews | 4.6 out of 5 stars 4,074 Reviews | | Included Components | 1x PT520A Gas Leak Detector, 1x Storage Bag, 3x AAA Batteries, 1x User Manual | | Item Dimensions D x W x H | 28.5D x 6W x 13.5H centimetres | | Item Weight | 0.51 Kilograms | | Item weight | 0.51 Kilograms | | Manufacturer | TOPTES | | Model Number | PT520A | | Operating Humidity | 80 percent | | Part Number | PT520A | | Power source | Battery Powered | | Product Style | PT520A Battery Operated | | Product dimensions | 28.5D x 6W x 13.5H centimetres | | Sensor Type | Electrochemical | | Style | PT520A Battery Operated | | Unit Count | 1.0 count | ## Product Details - **Alarm:** Audible, Visual - **Brand:** TOPTES - **Colour:** Orange - **Item weight:** 0.51 Kilograms - **Operating humidity:** 80 percent - **Power source:** Battery Powered - **Product dimensions:** 28.5D x 6W x 13.5H centimetres - **Sensor type:** Electrochemical - **Style:** PT520A Battery Operated - **Unit count:** 1.0 count ## Images ![PT520A - Image 1](https://m.media-amazon.com/images/I/718k6noTUgL.jpg) ![PT520A - Image 2](https://m.media-amazon.com/images/I/61L9A3dVPRL.jpg) ![PT520A - Image 3](https://m.media-amazon.com/images/I/611CY7eX0pL.jpg) ![PT520A - Image 4](https://m.media-amazon.com/images/I/71jTLj-3CXL.jpg) ![PT520A - Image 5](https://m.media-amazon.com/images/I/71WKZOvQmpL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Can this product detect nitrogen?** A: Thank you for your inquiry.

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.

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 ### ⭐⭐⭐⭐⭐ TopTes PT520A Gas Detector *by G***J on 9 November 2024* I recently purchased the TopTes PT520A Gas Detector for added safety in my home and RV, and I am very impressed with its performance.

Used to find a problem in a dual propane cylinder system. Works very well , though the display is difficult to read in the two days a year we have sunshine. 😁 Found the leak in five mins and fixed it safely. Can't comment on the sensitivity but very pleased as it saved me an engineer call-out for a simple fix. Well worth the cost. ## Frequently Bought Together - PT520A Natural Gas Detector, Gas Leak Detector with 17-Inch Gooseneck, Locating The Source Like Propane, Methane, and Butane for Home and RV (Includes Battery x3) - Orange - Kidde Carbon Monoxide Detector, Propane, Natural, Methane, & Explosive Gas Alarm, Plug-In Wall with 9-Volt Battery Backup, Digital LED Display - TopTes PT199 Natural Gas Leak Detector with Audible & Visual Alarm, Portable Gas Sniffer to Locate Combustible Sources Like Methane, Propane for Home(Includes Battery x2)-Orange --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co/products/518411373-pt520a](https://www.desertcart.co/products/518411373-pt520a) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-09-14*
