Featuring audible and visual alarms that activate within 0.5 to 3 seconds, it offers professional-grade sensitivity in a portable form factor with smart power-saving features and a 3-year warranty. ## Description How to Set Up the Detector for Accurate Readings? Before performing actual measurements, turn on the PT177 and allow it to warm up for 30 seconds (the warm-up process is mandatory). Please ensure the warm-up is conducted in a known "clean" environment to achieve accurate results. How can I tell what sensitivity the detector is currently at? When the S button light is on, the detector is in high sensitivity mode; when the S button light is off, the detector is in low sensitivity mode. Does the alarm continue until the situation is resolved? Yes, the alarm will continue to sound until the combustible gas concentration is below 5% of the lower explosive limit. I suspect a gas leak, but the device does not detect anything. What should I do? Please allow the PT177 to warm up in clean air for 30 seconds before testing. The device is designed for close-range detection (1–5 cm); greater distances may reduce sensitivity. Adjust your testing position accordingly for accurate results. Can the sensors be replaced? We do not sell sensors separately. If you find that the sensor is no longer working within three years from the date of purchase, please get in touch with us.

I found a very small leak at the stove pilot light supply fitting. I was able to tighten the nut almost a full turn, "no more leak". Well worth the price and detected a leak that had no discernible smell. ### ⭐⭐⭐⭐⭐ Discovered leak! *by on Reviewed in the United States July 20, 2026* Great product. Discovered a leak at new water heater ### ⭐⭐⭐⭐⭐ Must have!!! *by on Reviewed in the United States July 8, 2026* This is a lifesaver for an appliance technician when working on gas appliances. Easy to use, great price, and reliable, it keeps you and your customers safe. ## Frequently Bought Together - Natural Gas Detector, TopTes PT177 Gas Leak Detector with Audible & Visual Alarm, Portable Gas Sniffer to Locate Combustible Leak Sources Like Methane, Propane for Home (Includes Battery x2)-Orange - HSTMYFS Natural Gas Leak Detector, Plug-in Propane Natural Gas Detector for Home Kitchen RV, Combustible & Explosive Gas Alarm for LPG, LNG, Methane - Kidde Carbon Monoxide Detector, Propane, Natural, Methane, & Explosive Gas Alarm, Plug-In Wall with 9-Volt Battery Backup, Digital LED Display --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/512636050-natural-gas-detector-toptes-pt177-gas-leak-detector-with-audible](https://www.desertcart.tn/products/512636050-natural-gas-detector-toptes-pt177-gas-leak-detector-with-audible) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-23*
