Review on 🔎 Refrigeration Technologies-RT100S Big Blu Micro Leak Detector 1 Qt: Unlock Ultimate Precision for Refrigerant Leak Detection by Mark Greenwood

supplier has the best price but doesn't have stock (less than half the price). The spray comes in handy for a quick coil cover. I ended up finding my leak with a cheap leak detector. I had a leak at the end of an improperly clamped capillary tube. The heated tester quickly determined that bubbles do not form at the end of the tube.
