Special specifications

In addition to the standard model, it is possible to specify constituents, and if the small flow rate set, communication set, or NOx-NO switching solenoid valve set is provided.

Measurement components	1 constituent (NOx) or 2 constituents (NOx, O₂) (*5) O₂ cannot be measured if small flow rate set is selected. See small flow rate set page. NO and NO₂ can be measured as well as NOx if NOx-NO switching solenoid valve set is selected. See NOx-NO switching solenoid valve set page.
Measurement range	NOx: 0-25/50/100/250/500/1000/2500/4000 ppm O₂: 0-5/10/25vol% NOx measurement range differs if small flow rate set is selected. See small flow rate set page.
