Description
Overview
GAOTek infrared gas detector is a kind of hand-held instrument that can perform continuous measurement of gas. This leakage detector adopts imported gas infrared sensor, it utilizes unique method of data processing, and it has the functions of high sensitivity, quick response, good stability, automatic modification of zero drift as well as speech alarm output, etc. The hand-held design facilitates carrying and testing; light-emitting display screen of organic matter is adopted, and The display is clear without a lamp light when it operates at night.
