MGP261 methane, carbon dioxide, and water vapor measurements can be shown either as wet basis or dry basis values. The wet basis / dry basis measurement output selection is made when ordering the probe, and can be configured with Vaisala Insight PC software or Modbus.

The following formula shows the conversion between wet basis and dry basis values.

X ( d r y ) = X ( w e t ) 100 %   -   H 2 O
where:
X(dry)
gas concentration (dry basis) (%)
X(wet)
gas concentration (wet basis) (%)
H2O
gas concentration (wet basis) (%)
