*1: No carrier gas cylinder is required.
*2: Up to two ranges are supported for each component.
*3: Response time may vary depending on the sampling system composition.
*4: Support is available for -15 to 40 C (cold-climate version) and 5 to 50 C.
*5: An NH3 scrubber is available as an option for cases where a combined gas includes NH 3. SO2
measurement corrected for CH4 interference is available for cases where there is CH4 in the sample
gas for SO2 measurement. CO measurement corrected for N 2O interference is available for cases
where there is N2O in the sample gas for CO measurement.
