This report shows the sensitivity of all the major brand HVAC leak detectors in parts per million to CFC R22 and HCFC R410a. The report must be purchased to cover my expense of making it. But, it is worth every penny, because you will know what leak detector to use for the particular gas you are leak testing. The report is available on ebay. Just search for a leak detector and the report will pop up.
