The ALD-300 is a hand-held leak detector that uses the
infrared 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. ALD-300 is equipped with large LCD screen, so
that the test results are more intuitive. The exclusive desi-
gn of appearance is in accordance with human body me-
chanics to make it the best experience for users.
