Additional Notes: Above 85% relative humidity and 40°C, a maximum continuous exposure period of 10 days is warranted. The sensor will recover normal electrolyte volumes when allowed to rest at lower humidity and temperature levels for several days.

Figures and Diagrams: The document includes figures showing the sensitivity temperature dependence, zero temperature dependence, and long-term stability of the sensor. These figures illustrate the sensor's performance across different conditions and over time.
