1.2 Example of sampling system configuration
with IR800G/IR810G
The following is a general configuration example. Please contact us for details.

R
*1: For use of NO meters, SO
2
meters, and 0-200 ppm CO meters, be sure to use a dehumidifier such as an electronic cooler.
(approximately equal to 2°C saturation)
*2: The NO
2
/NO converter is used for NOX measurement.
*3: Whether or not a comparison gas purifier is required depends on the concentration of the measured component in the
comparison gas.
If the concentration of the sample gas in the reference gas is less than 0.1% F.S. of the range, a reference gas purifier is not
required.
If the atmosphere is used as the reference gas and the range is less than or equal to the ranges below, the use of a reference
gas purifier is recommended.
NO: 0-100 ppm or less, SO
2
: 0-50 ppm or less, CO: 0-1000 ppm or less
Contact Yokogawa for a reference gas purifier for each component.
Use N
2
as a reference gas for CO
2
(Low range): 0-0.1 vol% to 0-5 vol%. (Atmosphere is not acceptable)
