    Question Thermal Imager Usage

    Looking for alternative way to find refrigerant leaks, considering using a thermal imager as oppose to using electronic device. Have any of you tried this method and have had any luck?

    I have a thermal imager, Fluke Ti32 and have seen refrigerant leaks with it. But I dont recommend it over a tool that is designed to actually detect refrigerant.

    Thanks for the respnds, I use the Inficon D-TEK, I have trouble using it, seems like it gives false hits, and when I use bubble soap can never find it. I only seem to have luck with obvisous large leaks. Any helpful advice on leak detecting?

    Here are some leaks I've picked up with a thermal imager

    Picture 1: you can see a green/yellow fog coming from the left of the receiver liquid level gauge.

    Picture 2: You can see the camera picked up the liquid refrigerant leaking out of a pin hole in the Evap. As the bits of liquid refrigerant leak out of the tube, it cools the area of the leak, and the camera picks up the thermal differences. (this was a small leak)

    Picture 3 & 4 are much the same as 2. The camera picks up on the liquid refrigerant boiling off at atmospheric pressure. The camera low scale only goes down to -22.2*, so it marks the coldest spot in the picture with a <-22.2* because its below scale.
