Cross Sensitivities
The table shows the response of the sensor to other gases than target gas (cross sensitivities). The values are typical and apply to new sensors.
The table does not claim to be complete. Gas mixtures can be displayed as the sum of all components. Gases with negative cross sensitivity may
displace a positive reading of the sensor.
