In - situ Laser Process Gas Analyzer (Transmissive Type) KGD - MQ - 507 for Measuring Gas Concentration
Product Introduction
The KGD - MQ - 507 In - situ Laser Process Gas Analyzer is a high - performance optical analysis instrument based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology. It adopts a transmissive design and can be used for industrial process gas control. With a fast response time, which is generally calculated in seconds for in - situ measurement, it avoids the time delay caused by sampling - type measurement and can promptly reflect the concentration of the measured gas on - line.
