The ALD-50 Combustible gas Leak Detector is a hand-held
leak detector that uses the heated diode detection principle.
Compared with the traditional leak detector, its sensor has
a longer life, higher detection accuracy, easier to operate
and can detect a wider range of combustible. The ALD-50
has an ergonomic design and a large LCD screen for easy
viewing.
