Brief introduction The Process Gas Analysis System of LGA-4000 series (In-Situ model), based on the technology of the diode laser absorption spectroscopy (DLAS), is the gas laser analysis system with integrated design and high integration. The system, by in-situ measurement that needs no sampling pretreatment, is able to rapidly, accurately and reliably measure various industrial process gases and flue gases emitted for environmental protection, to provide the best solution for the on-line gas monitoring in various industries. Features 1. Laser In-Situ measurement, rapid response, high measurement precision; 2. Integrated positive pressure explosion-proof design, safe and reliable; 3.Modular design, with the possibility to renew all functional modules on site, easy to maintain; 4. High intelligent interface, easy to operate. Technical parameter Technical indexes Linearity error: ≤±1%F.S. Span drift: ≤±1%F.S./half-year Repeatability: ≤±1%F.S.
