The LGT-510 Laser Gas Analysis Module is a free-standing gas detection product based on TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology, which is suitable to be integrated in monitoring system and applied in various occasions. This module can be customized according to actual field. It is able to measure O2, CO, NH3, H2S, CO2, CH4, H2O, HCl, HF and other gas from regular concentration to trace amount. With the characteristics of high accuracy, low cost, easy to OEM customer integration and so on.

The LGT - 510 laser gas analyzer uses the tunability of laser wavelength to make wavelength varies with the change of working temperature and current. By the periodic modulation of the current, the laser wavelength can be periodically changed within a small range, and the 'single line absorption line' data of the measured gas can be obtained in each cycle.

At present, TDLAS technology has developed into a high sensitivity, high resolution, high selectivity and fast response gas detection technology, which is widely used in molecular spectroscopy, industrial process monitoring and control, combustion process diagnosis analysis, engine efficiency and vehicle exhaust measurement, safety control, monitoring of trace contaminated gases in the atmosphere and other fields.

  • Modular design, easy to be integrated and maintain
  • Small size, light weight, easy to carry
  • Single line spectral absorption, high accuracy
  • Easy maintenance: product modular design; easy installation and maintenance
  • Low detection limit: Use multi-channel reflection measurement absorption cell; lower detection limit
