## Description

desertcart.com: 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 : Industrial & Scientific

Review: Accurate and Good Price - For the price, this item works great. It is not a detector that sniffs the air for readings like the long probes you see energy companies have. It is a smaller device that works well for testing for natural gas leaks at the source. This means you must hold it gently against an area that you want to check for a moment. It is great for checking around valves or other seals that could leak gas such as your water heater tubes or gas stove. I had a 1lb propane tank shut off and it was able to detect residual propane on the tip of it, which is what Xcel energy did one time with their probes in front of me, so if it can catch that, it likely will catch other non-smelling leaks, but you must go slow around the areas you are testing and also turn the S on for sensitive.
Review: Pocket size natural gas leak detector - This device does require a 30 second zero level calibration each time you turn it on. I used it to detect and pinpoint a natural gas leak around the gas valve controller on my water heater. Very easy to use and was very effective. The display and audible alarm quickly reveal how much gas is being detected. I thought the price was good too.

## Questions & Answers

**Q: Can I travel internationally with this device?**
A: There is no restriction on traveling with these.  The only issues may be:
- customs trying to tax you for importing the device
- immigration using the device to prove your intent to work in country without the appropriate visa
If I found such a device in baggage inspection, I might ask why you had it and to demonstrate its use to make sure it wasn't a disguised prohibited item.

**Q: Does this product can find r600a leaking ?**
A: No, I would get the Elite h WJL-6000S Refrigerant Leak Detector. I think that might be what you want.

**Q: Does this detect vaping and cigarettes?**
A: Thanks for your question.
TopTes PT199 gas detector may not detect vaping and cigarettes.

Vaping and Cigarettes are not combustible gases.
vaping contains e-liquids vaporized under the heating environment.
In cigarettes, tobacco leaves are burned to generate the smoke.
Their results are also not combustible.
Vaping aerosols include nicotine, propylene glycol, vegetable glycerin, flavorings, and other additives.
Tobacco smoke contains tar, CO, formaldehyde, benzene, and other carcinogens and toxicants

Yet, when air humidity is too high, it may trigger false alarms from combustible gas detectors.
Thus, it is not recommended to detect vaping and cigarettes with TopTes PT199 gas leak detector.

**Q: Can you use rechargeable batterys?**
A: Rechargeable lipo batteries are 4.24 volts when fresh off the charger. Are you [seller] saying that this device will accept that voltage?
