Accutrak VPE Standard Kit Ultrasonic Leak Detector

Really did a great job finding refrigerant leaks. Found two leaks in a very expensive machine that me and a factory tech could not locate with a sniffer. Found them with system pressurized with 200 PSI of nitrogen. Also bought a Chinese $130 unit to compare and that one could barely locate the leaks even after I knew where they were.

As $650 leak detector I fell disappointed. It maybe works for other situations but the leak I tried to addressed couldn’t found by this leak detector. I assume this leak detector couldn’t catch small leaks.

Not at all what I had hoped for. The only refrigerant leaks you are going to find with this are ones that you can hear without equipment and is a lot easier to just use a refrigerant leak detector or bubbles. After months of not using it and taking up space in the van, I tossed it in the corner of the garage.

Found a leak in an attic a-coil that regular leak detectors would not pick up, even with trace gas and nitrogen, in about two seconds…

Very fast to detect leakage.Good device comparing to price.
