Product Details
KF200 Laser Gas Analyzer
Product Description
The KF200 Series Laser Gas Analyzer is specifically designed for
industrial online monitoring and continuous environmental emissions
measurement. Utilizing Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology, the analyzer features a highly integrated, compact
design for reliable and precise gas detection.
The KF200 series offers a variety of configurations, including in-situ probe, bypass, multi-channel, and disc-mounted models, allowing the analysis of gases such as O₂, CO, NH₃, CO₂, CH₄, H₂O, HC, HF, and others. It supports both macro-level and trace-level concentration measurements, providing versatile solutions for different industrial
applications.
Technical Principle
The system scans the specific absorption peak of the target gas by
modulating the laser wavelength through controlled current and
temperature. Background gas interference is eliminated, and the
analyzer measures the second harmonic signal of gas absorption. Using this signal along with gas broadening
information, the precise concentration of the target gas is calculated.
Technical Characteristics
Employs TDLAS technology for real-time, in-situ gas analysis.
Features a dual-protection probe design that eliminates the need for positive pressure purging or
additional data processing units, offering a compact, simple, and highly reliable structure.
Utilizes high-power lasers without fiber coupling, making it suitable for harsh industrial environments, including high dust conditions.
