Fieldpiece - DR82 Infrared Refrigerant Leak Detector - Ultra-Sensitive Leak Sniffer with Large, Backlite LCD Screen - Lightweight HVAC Tool

Works great! I have found leaks on R410A systems and it works with R32 and R454B as well! There hasn’t been a leak I haven’t been able to find with this thing. From mini splits, coils, and braze joints it has found micro leaks on all systems. Great tool that saves time and money. Every system had at least 100PSI of standing pressure in it. Take that for what it is worth. Not sure how low a system can be before it detects the refrigerant but I was very surprised. Easy to use, case makes for great storage on the shelf and portable on job sites.

Best leak detector on the market

This an excellent detector. The filter in the tip is way to restrictive but a small pin hole in the filter fixes it

Does a great job finding leaks. Small leaks is not a challenge for this detector. Recommend this to anyone working in HVAC field

First, this is an amazing leak detector! It's incredibly accurate and so easy to use; you can't beat it! 5 stars for the leak detector! Buuuut.... it happened to be sent to me with a complete set of European power adapters, but alas no US power adapter. Its covered by product support, so I called them to simply have them send the proper adapter that it should have came with, but NOOOOOOOO, Amazon can't do that, its too difficult a concept for their foreign customer service personnel to grasp. They have only one option memorized: just send it back and reorder it. And, if you've ever done such a thing, you know that A) you're simply gambling that the replacement item sent will be correct, and B) you can guarantee that you'll be paying more for the replacement item when you reorder it - a fact that they quite capably exposed me to just a few short weeks ago. Better still, you don't get your purchase funds refunded for up to a couple of weeks (hopefully) while you're paying the new amount for the replacement, so hopefully you have enough credit space on your account to cover this error. This resolution process is sophomorically stupid and unnecessarily costly. If they simply sent the silver dollar-sized part that it should have originally came with, it would only cost a matter of perhaps a dollar or two. Instead, they'd rather inconvenience their customer with the loss of the tool for at least a week, the customer picks up the new cost, and Amazon is now picking up an additional shipping bill which it will happily pass on to its customers.

Works great. Sniffs out small R134a leaks on my 1989 VW vanagon.

Amazing leak detector. On the max sensitivity it doesn't have the false alarms I thought it, but using it can find eve tiny leaks, and then dialing it down I've been able to pinpoint every leak I found without even using bubbles. This is the best leak detector I've used so far under $500.

I bought this as a backup since my stratus needs to be sent in for repair. This product works great. No regrets buying it. I've already found a small leak in an EVAP coil. Very nice product.
