As some of you know, my van disappeared from a parking lot in Northeast Philly nearly two years ago. Most of the tools have finally been replaced.
The first leak detection tool I replaced was my Amprobe ultrasonic listening device. I just pressurize with N and listen for the sound. I'm surprised at how effective it has been.
There are times, though, when I miss my old CPS Leak seeker 790A. Of course, that was a holdout from the early 1990's.
Now, I keep hearing about varying opinions about the H10 and the D-Tek brands. Apparently, like Neumann microphones, not all H10's are seen as equal.
So, I'd like to hear your recommendations, with reasons given, for a leak detector to add to my truck.
Common refrigerants being used include:
R22, 410a, 404a, 134a.
If you had to buy a leak detector "tomorrow," which would you buy, and why?
