Principle ：
laser gas analyzer using a Tunable Diode Laser Absorption Spectroscopy (TDLAS), the realization of the non contact measurement in high temperature, high pressure, high dust and other harsh test conditions. High selective laser based on frequency, analyzer has good performance of anti interference. compared to the traditional analysis method, reducing the complex sampling system, flexible installation and easy to use, greatly reduce the manual installation and maintenance workload
