The KF200 Series Laser Gas Analyzer is developed aiming at industrial on-line analyzing and online environmental monitoring. Based on the semiconductor laser absorption spectros capy (DLAS) technology,
it is developed with features of an integrated design and high level of integration.
With various types of the KF200 series laser gas analyzer, including in-situ probing type, by-pass type,
multi-channel and disc-moulted type, etc., gases like 02, C0, NH3, CO2, CH4, H2O, HC, HF etc., can all be
analyzed. The concentration analyzing of target gases includes the macro-analysis and micro-analysis.
>>>Technical Principle
Modulate laser (tunable) wavelength by using the current and temperature to scan the specific absorption peak of the measured gas (no background gas absorption), and then get the second harmonic of the gas absorption. By using the second harmonic information and the broadening of the gas, the concentration of the gas can be calculated.
