eLAS-T Series Laser Gas Analysis System

Classification：

eLAS Series

Product Description:

The eLAS-T series of laser gas analysers uses an integrated in-situ extraction measurement method, which integrates the high temperature sampling probe and high temperature detection pool. The whole process of high temperature, Heliot-cell structure, to achieve high precision gas detection. The sampling pipeline and sampling gas transmission process in the traditional extraction system are cancelled, and the whole system is directly installed on the flue, which reduces the sampling loss of flue gas. The system is "small" but "precise", not limited by installation point and operating conditions, the sensitivity and resolution of the measurement is very accurate. It can realize online calibration to ensure the high precision and high reliability of gas monitoring. It is suitable for a variety of application sites. It can also realize the multi-point measurement of the measured gas according to customer requirements.
