1.3. Minimum Measurable Dew Points

The minimum dew point that can be measured is determined by the sensor temperature, and
whether the sensor can be maintained at that temperature. The following chart assumes
operation in a climatic chamber, where the air speed is sufficient to remove any excess heat
generated by the sensor.
