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.
