LD-200 Heating Diode Handheld Leak Detector Air Conditioning Refrigeration Syste

The LD-200 is a hand-held leak detector that uses the heated diode detection
principle. Compared with the traditional leak detector, its sensor has longer life, higher detection accuracy, easy to operate and can detect a wider range of refrigerant. LD-200 is equipped with large LCD screen, so that the test results are more intuitive. The exclusive design of appearance is in accordance with human body mechanics to make it the best experience for users.
