The Mastercool Thermal Imaging Camera, No. 52300, can measure from -20 to 250 degrees C (-4 to 482 degrees F) and display thermal images and temperature. Thermal images can be saved to a micro SD card and transferred to the software included for image reporting. The unit is fully automatic and focus free. Automotive applications include tire contact and wear diagnostics, brake and engine system evaluation for performance and cooling, rotor temperatures and wear patterns, search for faulty fuel injection nozzles and faulty wheel bearings, passenger compartment A/C comfort analysis, A/C liquid and gas lines and hose analysis and searching evaporators, condensers and radiators for proper heat exchange.
