    Thanks. Iíve heard some good things about the tekmate

    Just another random gripe: donít look for a leak after youíve washed the outdoor coil with renewz. Found out the hard way awhile back on a maintenance.

    I usually wash the coil first thing so it has a chance to dry and I can check the charge with a known clean coil. I found the system low and got approval for leak search. Started indoors and sure enough, fin pack leak.

    Checked lineset and when I pulled the top to check the coil and tubing, I couldnít even get the detector inside the cabinet before it started screaming. With some experimenting, some head scratching and some wasted time i figured out it was the cleaner residue on the bottom of the pan. Had to wash it a few more times with the hose and remove all debris before I could check it.

    D-Tec Select. Best detector Iíve ever used. If it doesnít beep, there is no leak.

    The only other detector Iíd consider is the H-10.

    The inficon i tried recently did good with the h10 reference bottle. Not near as good as the h10 though in practice.

    Select is horrible. H10pro is great for 22 and ok for 410a.
    Slr8 is great for 410a and horrible on 22.
    The select barely picks up anything compared to those 2

    I have an older H10 (not PRO) I use for R22... seems to be more sensitive to 22 than the newer PRO...

    For 410... use the H10 PRO... seems to wok better on 410.

    Yeah, the H10's are expensive... however they just work!

    Anyone have one of the old H10 plug in models... it is really sensitive to 22... however has to be plugged in and is kinda finicky to work with... got mine years ago from another contractor...

    I must have gotten a rare one, because in 5 years, my D-Tek Select has never missed a leak. I’ve had others, and never trusted them. Too many false alarms. With the Select, if it goes off, there is refrigerant. Every time.

    a lot of leak detectors are set off by Big Blue and other leak detection products. The SLR8 is set off if you breathe in front of the sensor.

    As others have said, the SLR8 works better on 410a. I use the SLR8 for 410 and a TIFZX for R-22.

    Thank god for big blue. I had an R22 system with a 3 lb leak today. SLR8 couldnít find anything. Sprayed all the indoor coil copper joints and found a bunch of small leaks with one or two larger ones.

    If I wasnít so broke Iíd go and buy a tekmate. But, Iím broke
