I've been using a SRL8 for a while now. In the last few years, there have been leaks that I just haven't been able to locate (plus the fact that Leak Lock & Nu-Calgon Flour. leak detector set off false alarms...). I put in a new sensor a few months ago. It's sensitive to small test leaks. Last week, I got called out to a job with a 5 ton system that I put 5 lbs of r22 in last may and it was 8 lbs low. 8 lbs in 9 months...that shouldn't be a problem to pick up. The condenser's on the roof and most of the 60 ft or so of the line isn't accessible, so maybe it's somewhere in the walls, but frankly, I've had some other 22 systems where it wouldn't find a leak. I don't seem to have that issue with r410, but we have a lot of r22 systems in this city.
At any rate, I'm going to pick up a 2nd leak detector and go back. Any suggestions for a decent detector that will balance out the SRL8 (particularly for R-22)?
Thanks!
