## Questions & Answers

**Q: How to Set Up the Detector for Accurate Readings?**
A: 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.

**Q: How can I tell what sensitivity the detector is currently at?**
A: 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.

**Q: Does the alarm continue until the situation is resolved?**
A: Yes, the alarm will continue to sound until the combustible gas concentration is below 5% of the lower explosive limit.

**Q: I suspect a gas leak, but the device does not detect anything. What should I do?**
A: 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.

**Q: Can the sensors be replaced?**
A: 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well and is a great value.
*by T***N on April 17, 2025*

This item is easy to use. Just insert the batteries, secure the cap, and press the red power button. When the unit turns on you’ll see lights. Wait 30 seconds, during that time the system will calibrate and the lights will flash from low to high. When the calibration is complete, the flashing will stop. I pressed the green button once to see the sensitivity level and then tested it on a Mapp gas valve that I opened just for a fraction of a second, and Beeeeep, the alarm went off. The function was excellent. The leak was detected without complication. I proceeded to check my other tanks of propane and acetylene. No leaks after performing the same open and closed valve procedure. For more details, please read the manual and follow the directions. If you’re in doubt about the readings or lack thereof. Or if you smell gas but the detector doesn’t, be safe and make sure all valves are closed and consult a professional. In addition to this detector, I use two other detectors for combustible and non-combustible gases - some gases rise and others sink to the floor such as carbon monoxide. For multilevel structures, use multiple plug in sensors, keep a portable detector like this one nearby the gas sources for a quick check before and after switching tanks. No tank should ever be assumed to be leak-free. Be safe!

### ⭐⭐⭐⭐⭐ Very nice gas detector
*by L***E on July 22, 2025*

Works great! It helped me find a leak in my oven gas connection!

### ⭐⭐⭐⭐⭐ Good sensitivity, good price
*by D***Z on May 20, 2025*

I am thoroughly impressed with this for it's price point, had a propane leak that I could not find with the old soapy water trick but showed up if gas was left open over enough time, it really did help me pinpoint the connection that was troublesome, it does take a few seconds when the leak is small and it is at high sensitivity mode, but it really did the job. For the price point it is a good tool to have handy if you do anything with gas systems.
