A method for testing for fluid leaks between plates in a plate heat exchanger without dismantling is disclosed. A camera 8 that is capable of producing a thermal image is positioned near the plate heat exchanger 1. By moving the camera around either mechanically or manually the heat signature of various locations in the plate heat exchanger can be measured. Any leaks present will show up as a large temperature difference on the heat signature. The invention has particular application to the dairy industry.
