DLAS Laser FID Hydrocarbon Process Gas Analyzer For O2 CO NH3 CO2 Monitoring
Laser Gas Analyzer for O2 Co Nh3 CO2 Gas Monitoring and Analysis
>>Overview
The AG-TDL07 Laser Gas Analyzer is developed aiming at industrial on-line analyzing, and online environmental monitoring. Based on the semiconductor laser absorption spectroscopy (DLAS) technology, it is developed with features of an integrated design and high level of integration.
With various types of the AG-TDL07 laser gas analyzer, including in-situ probing type, by-pass type, multi-channel and disc-mounted type, etc., gases like O2, CO, NH3, CO2, CH4, H2O, HC, HF, etc., can all be analyzed. The concentration analyzing of target gases includes the macro-analysis and micro-analysis.
>>Feature
1. Adopting the DLAS technology, the in-situ online gas analyzing
2. Double proof probe design, without positive pressure purge, no additional data processing unit, simple compact structure, high reliability
3. Using high-power lasers, no fiber coupling, anti-hash working conditions (such as excessive dust condition)
4. Using patented technology of spot light path adjustment, easy for on-site installation
