5.3.1 47K-HT-PRP
Relative response factors of tested gases with reference to Propane.
These values are only valid for new sensors and, unless otherwise stated, refer to
an ambient temperature of 110 °C. In this case the displayed values may vary by
up to ±20% from the target gas concentration.

5.3.2 47K-PRP
Relative response factors of tested gases with reference to Propane.
These values are only valid for new sensors and, unless otherwise stated, refer to
an ambient temperature of 20 °C. In this case the displayed values may vary by
up to ±20% from the target gas concentration. Response times stated in the
enclosed table may vary by ±20% depending on the tolerances of individual
sensors.
