eLAS-T Series Laser Gas Analysis System

Classification：

eLAS Series

Product Description:

The eLAS-T series of laser gas analyzers uses an integrated in-situ extraction measurement method, which integrates a high-temperature sampling probe and a high-temperature detection cell. The high temperature detection cell adopts the Heliot optical cell structure to achieve high precision gas detection. The sampling pipeline and sample gas sampling transmission process in the traditional extraction system are cancelled, and the sampling loss is reduced by directly installing on the flue. The system is highly integrated, not limited by the installation point and working conditions, and the measurement sensitivity and resolution are high. On-line calibration can be realized to ensure high precision and reliability of gas monitoring. Multi-point measurement of the measured gas can also be achieved according to customer requirements.
