ZRE Infrared Gas Analyzer
-Simultaneous and continuous measurement of the concentration of up to 5 gas components.
-Excellent prolonged stability
-Compact size and simple operation
-Virtually unaffected by the inerference of moisture.
-Substantial functions, including automatic calibration, communications, and alarms(Option)
Measurement principle
-NO, SO2, CO, CO2, CH4 : Non-disersive infrared ray absorption(Single-beam system)
-O2 : Fuel cell(built in) or zirconia (Externally installed ZFK7 by Fuji)
