Overview
Explosion proof laser gas online analysis for waste incineration flue gas monitoring. The x series explosion-proof laser gas analysis system adopts a positive pressure explosion-proof cabinet to isolate flammable substances from the ignition source, achieving explosion-proof purposes. The analysis system is based on the principle of tunable semiconductor laser absorption spectroscopy (TDLAS) technology, which scans and analyzes gas absorption spectral lines of specific wavelengths, and combines advanced technologies such as digital lock-in amplifiers and long path gas chambers to achieve gas concentration measurement

Explosion proof laser gas online analysis for monitoring of waste incineration flue gas
Product Introduction:
The Ex series explosion-proof laser gas analysis system adopts a positive pressure explosion-proof cabinet to isolate flammable substances from ignition sources, achieving explosion-proof purposes. The analysis system is based on the principle of tunable semiconductor laser absorption spectroscopy (TDLAS) technology, which scans and analyzes gas absorption spectral lines of specific wavelengths, and combines advanced technologies such as digital lock-in amplifiers and long path gas chambers to achieve gas concentration measurement. The instrument has the characteristics of high sensitivity, fast response speed, no background gas interference, non-contact measurement, etc., providing a reliable guarantee for real-time and accurate reflection of changes in the measured gas.
Product Features:
1. Spectral multi wavelength scanning without cross interference from background gases
2. Reliable long path detection cell design ensures measurement accuracy
3. Fast response time
4. Non contact measurement, with a service life of 10 years
5. Easy installation and maintenance, low usage cost
Typical applications:
1. Hydrogen sulfide detection in natural gas pipelines
2. Monitoring of hydrogen sulfide in incineration flue gas
3. Process control in chemical engineering
4. Pollution source emission monitoring
5. Monitoring before and after desulfurization
