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