HVAC Business Owner here. I bought this because I was certain it was going to be a good leak detector as NAVAC usually makes great products. I was able to put this to use on a Fujitsu Mini Split system that had 2 big leaks at the condenser (2 flair joints). This didn't detect any refrigerant at either joints. I brought it to my refrigerant tank to make sure it worked to rule out that it wasnt faulty – and it work. I am far from satisfied with this product.
