TEK-Mate

Works as described!!!

You get what you pay for. This sniffer works like you expect, no false positives for me at least, it's a very effective tool. Stay away from the 25 dollar el cheapos, I have one of those and it went off on the carpet in my vehicle, and I'm pretty sure the floor mats did NOT have a leak. Just save your pennies and buy one of these.

Works as it should

Works good for detecting leaks. Sometimes it may take 2+ minutes to calibrate and sometimes it calibrated in 30 seconds.

Tested with a bottle of 410a, cracked it just a tad like a tad and this thing is sensitive might need to take cover off furnance and let I breath or I could see it going on before your over the leak- will update if any issue but definitely works, comes with a updated sensitivity sensor I may take out we will see. But again it works and I'd get it if you need a decent tester. Comes with some sponge tips also incase it gets grimly you can replace these.

It finds the leaks, just make sure you install the sensor before checking for leaks

Large and clunky feeling .

I selected Inficon's TEK-Mate 705-202-G1 as my first refrigerant leak detector in preparation to enter the HVAC/R field. It's the only "real" leak detector I own (the other being an extremely inexpensive no-name halogen type). I haven't used it more than a handful of times, so take this review accordingly. I've used it in residential, commercial (walk-in cooler) and automotive applications so far. It's very sensitive -- maybe even too sensitive for its own good. Even on the low setting, I had a hard time pinpointing what was a very small leak in the evaporator coil of the walk-in box. I like the fact that it's made in the USA and came with name brand alkaline batteries, so you can get started right away. The built in alarm is very loud. You might like that if you're working in extremely (and I mean extremely) noisy machine rooms. I thought it was too loud for every other situation, and the constant wailing of the alarm during the sensor's start up period really got on my nerves. If I didn't think I'd invalidate the warranty by doing so, I'd pop it open and put something over the beeper to quiet it down a little.

I was trying to chase down a very slow AC leak in my car was certain it was the compressor shaft seal or evaporator. Within 5 minutes I found the leak coming from my condenser which was replaced previously but was a defective part. Very happy with this tool !
