KF200 Bypass UV Gas Analyzer for High Dust Environment
The KF200 Series 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 deceloped 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-mounted type etc., gas 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.
>>> 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.
>>> Technical Characteristics
· The TDLAS technology is adopted for in-situ online gas analyzing;
· Double-proof probe design negates positive pressure purge, with no additional data processing unit, a simple compact structure and high reliability.
· Using high-power lasers, no fibre coupling, suitable for harsh working conditions(such as excessive dust);
· Using the patented technology of spot light path adjustment, easy for on-site installation.
