Contact Sensirion for information about other gases, wider calibrated temperature ranges and higher storage temperatures.

See section 5.1. The scale factor may vary with other configurations.

Instead of the standard scale factor (to get the physical value in Pa), the sensor output may be divided by alternative scale factors to receive the physical

value in another unit.
