KGD - MQ - 518 Laser Trace Moisture Gas Analyzer
Product Introduction
The KGD - MQ - 518 Laser Trace Moisture Gas Analyzer is a high - performance optical device for measuring gas humidity. It has advantages such as high measurement accuracy, fast response speed, high sensitivity, stability and reliability. It features alarm output, analog signal output, and rich communication interfaces, and supports the display of humidity volume ratio and dew - point value. It is suitable for dew - point detection in cryogenic processes of natural gas liquid (NGL) recovery units and in the production of liquefied natural gas (LNG).
