Overview
Product Overview: The laser greenhouse gas analyzer is based on the principle of tunable semiconductor laser absorption spectroscopy (TDLAS) technology, which scans and analyzes the absorption spectral lines of greenhouse gases such as carbon dioxide and methane. It uses digital lock-in amplifiers and long path gas chambers to achieve high-precision and high stability measurement
Product Details
Product Overview
laserGreenhouse gas analyzeryesBased on tunable semiconductor laser absorption spectroscopy（The principle of TDLAS technology,Scanning analysis was conducted on the absorption spectra of greenhouse gases such as carbon dioxide and methane, and high-precision and stable measurements were achieved using digital lock-in amplifiers and long path gas chambers. Tunable semiconductor laser absorption spectroscopy is based on the wavelength characteristics of semiconductor lasers, which can achieve high stability continuous measurement, especially suitable for online continuous monitoring and measurement of greenhouse gases.
Product Features
1) Using TDLAS high-resolution spectroscopy technology, the measurement is not affected by interference from other gases, which can effectively reduce the interference of dust or background gases;
2) It has the advantages of fast response speed and high sensitivity.
3) The measuring instrument has small drift, simple maintenance, and can operate stably and reliably for a long time.
Typical Applications
1) Monitoring of greenhouse gases from pollution sources
2) Environmental air greenhouse gas monitoring
