⭐⭐⭐⭐⭐  Robert R.

✔️ Verified Buyer

Compact hand held gas leak detector. The easy to use device can detect methane, propane, butane, ethylene, ethylene oxide and coal gas. The high precision detector has a two second response time as well. The battery operated device makes installing gas appliances so much safer!

⭐⭐⭐⭐⭐  Gearson H.

✔️ Verified Buyer

I’ve been using this leak detector for a few weeks now and it’s been super reliable. The sensitivity adjustment is great. I was able to track down a small R410A leak that I probably would’ve missed with my old detector. The screen is clear and easy to read, and I like that you can mute the alarm when working in tight or noisy spaces.

 

 

⭐⭐⭐⭐⭐  Rodriguez R.

✔️ Verified Buyer

I was slowly being poisoned by freon leaking into my apartment from the ac unit which was inside my unit. I was becoming sick and kept smelling an odd chemical smell. Despite mechanics coming and saying it was okay and I was delusional, I purchased this device and immediately found the leak myself!!! It saved my life! The high sensitivity setting is really nice and it’s easy to use.

 

⭐⭐⭐⭐⭐  Pietro R.

✔️ Verified Buyer

I purchased this item to find a refrigerant leak that several local hvac companies refused to find and repair(but they all gave quotes to replace a very long run of copper lines). This "sniffer" found the leak in less than 45 minutes. Well worth the price. I bought this one from a recommendation from a friend who runs a crew of hvac techs.

 

⭐⭐⭐⭐⭐ Thompson H.

✔️ Verified Buyer

I've used this tool for well over a year now and there hasn't been one leak I haven't found with this tool. 9.9 times out of 10, if this leak detector is going off, it has found an issue. Very accurate. It's the most reliable electronic leak detector I've had and well worth the money. I have found leaks deep within evaporator coils, condenser coils. Very simple and easy to use.

⭐⭐⭐⭐⭐ Harrison R.

✔️ Verified Buyer

This is great leak detector for the money. As with all leak detectors adjusting the sensitivity (calibrating) is very important to get accurate results. This sniffer is very sensitive witch comes in handy when in hard to see or reach areas. The probe is nice sized and also ridged enough to sneak into difficult places. The tone is loud enough, and lights alert you when it comes across a leak in the system.
