Product Description
Accurate, Reliable KF-200 Tunable Diode Laser Analyzer 

Accurate, Reliable Kf-200 Tunable Diode Laser Analyzer
>>> Product Description 
KF series Laser Gas Analyzer developed aiming at the industrial on-line analyzing, environmental on-line monitoring.
Many types of the KF series Laser Gas Analyzer are available, including in-situ probe, by - pass type, multi-channel and Disc mounted type etc.Gas types like O2,CO,NH3,CO2,CH4,H2O,HC, HF etc. can be analyzed. The  concentration analyzing of target gases contains the macro-analysis and micro-analysis.
