Tunable Diode Laser (TDL) Gas Analyzer SR-2030
Tunable diode laser (TDL) gas analyzer utilizes diode laser absorption spectroscopy (DLAS) technique. Compared to other techniques such as NDIR, gas chromatography, the result of DLAS will not be disturbed by H2O. What’s more, it features low cross sensitivities, higher resolution and higher accuracy. Thus, it has been widely acclaimed in the field of industrial process analysis, environmental pollution detection, etc.
Gases to be detected
CO, O2, CH4, CO2, etc
Application areas
Chemical fertilizer, chemical industry, metallurgy, building materials, thermoelectricity, air separation, power plants, cement, environmental protection, medical and other industries.
