The ALD-40 is a hand-held leak detector that uses the in-
frared spectrum absorption 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 carbon dioxide. ALD-40 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.
