Ex series explosion-proof laser gas analysis system

Ex series explosion-proof laser gas analysis system

Classification：

Ex explosion-proof Series

Product Description:

Ex series explosion-proof laser gas analysis system uses positive pressure explosion-proof cabinet to isolate combustible substances and ignition sources to achieve explosion-proof purposes. The analysis system is based on the principle of tunable semiconductor laser absorption spectroscopy (TDLAS) technology to scan and analyze the gas absorption spectral line of a specific wavelength, and combines advanced technologies such as digital phase-locked amplifier and long-path gas chamber to achieve gas concentration measurement. The instrument has the characteristics of high sensitivity, fast response, no interference from background gas, non-contact measurement, etc. It provides a reliable guarantee for accurately reflecting the change of measured gas in real time.
