Had a new furnace installed and could faintly smell gas from time to time. Tried soapy water and leak detection liquid from plumbing supply house but couldn't find it. Bought the PT520A and started checking the gas joints and found the leak within two minutes. It was in a connection under the gas valve that I couldn't really get to with my detection solutions. The PT520A is very easy to use and clearly tells you when gas is detected. It is basic. There is no readout telling you the concentration of gas but the audible alarm and bar graph give you a general idea. In my case it worked very well to locate the leak and is worth the money. I would recommend it for a cheap detection devise for around the house or camper. And yes, I did call the furnace installer and they responded within 2 hours to correct the issue. Review: Could save your life - This Gas Leak Detector comes in a very nice protective case and the 3 brand-named batteries are included, easy to read and understand instructions, so you can use it right out of the box. I purchased it because I have a propane tankless hot water heater, and my family and I started smelling rotten egg smells in our garage where the tank is located. We called a plumber, who fixed the tankless water heater, but not the source of the smell, so it seemed. We left the garage door open, then turned to desertcart for a Gas Leak Detector and this one met all of our needs and was reasonably priced. Within less than 24 hours of ordering it, it was in our home sending out an alarm as it picked up deadly propane in the air. We immediately called 911, the firemen's professional sniffer detected the same, and the Firemen took actions to ensure we were safe to stay in our home while we waited on the plumber. The plumber came back the very next morning and said he had purchased a Gas Leak Detector for over $200 on the way to our house, and it too found a propane gas in the air. It wasn't long after that the problem was found and fixed. We had used our detector and ran it along the Water heater and then along the main supply gas line and the signal became stronger the closer we got to a certain area. The plumber's detector did the same thing in the same area and sure enough there was a small but deadly hole in the metal coil gas supply line. Based off of how well this Gas Leak Detector preformed for our needs, I would recommend it for a propane gas leak detection as it states in its description. However, if you think you smell something rotten and you have propane for any reason, DON'T do as we did. Please call 911 first, keep doors and windows open and then buy this! It's a great gift to give to someone who has propane use in their home as a housewarming gift or Christmas stocking stuffer too. ## Features - Effective Gas Leak Detector: The TOPTES PT520A natural gas detector detects leaks of methane, propane, natural gas, LPG, butane, and more in tight spaces - Flexible Probe: The 17-inch gooseneck allows easy access to hard-to-reach areas like pipelines, storage tanks, gas fireplaces, and basements, ideal for both indoor and outdoor leak detection.

It is not intended for continuous monitoring and should be used only to localize the source of a leak during routine checks. **Q: Why do I choose gas leak detectors with gooseneck?** A: With gas leak detectors with probe, you could detect the leaks in hard-to-reach areas. Besies, gas leak detectors could protect your life by prventing potential dangers suc as fires or explosions and alerting the presence of toxic gases. **Q: Where could I use TopTes PT520A gas leak detectors?** A: In most hard-to-reach leaks, you could use TopTes PT520A to detect. Besides, natural gas pipelines, gas stoves, ovens, funaces, water heaters, gas storage tanks or gas lines are the most common places for gas leaks. **Q: Why does the TopTes PT520A need to warm up for 30 seconds?** A: Allow the 30-second warm-up to finish in clean, fresh air so the sensor can stabilize and deliver accurate readings. Warming up in an environment with gas present may affect the sensor and lead to inaccurate or delayed detection. **Q: Does a slower response time of the PT520A during testing mean my device is defective?** A: No. Variations in airflow, distance, angle, or gas movement can cause one detector to respond slightly sooner or later. This is normal, not a defect. For best results, keep the probe 1–5 cm from the leak point and move it slowly. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked Great *by J***M on March 6, 2026* It worked great to locate a very small LP leak.
