Back in the early 90’s I read an article about the U.S. Navy’s evaluation of electronic leak detectors. Their findings were that the heated diode sensor yield the most consistent reliable results. Corona discharge sensors were affected too much by other chemicals such as those added to leak detection solutions to prevent freezing.

On small leaks ultrasonics can be enhanced by spraying the suspected leak location with water. The water creates a surface tension trapping the refrigerant. A popping or snapping sound is picked up by the ultrasonic when the refrigerant breaks the surface tension of the water.

My H10 has issues with R410 and R407C. For the newer blends I use a Dtek

Yeah, that is the one. Mine is ancient. I love it! Those higher pressures make me think we are going to have leaks quicker.

Do you use digitals all day long? I am thinking of getting some, no one in my area uses anything like that.

I am halfway through your videos, thanks I am getting through my trouble shooting a lot quicker and with more confidence. Thanks.

..if the GE is what I think, it’s similar to the Johnson H10 I have (110 V corded)…They (H10’s) are supposed to detect HFC’s, but I had difficulty locating a 410A leak with mine, though it could have been operator error…

I’m using about a 1980 GE and I like it a hole lot better then the battery powered ditech the boss had. How do you think they are going to fare w/410?
