Notes:
1. Recommended humidity operating range is 20% to 80% RH (non-condensing) over –10 °C to 60 °C. Prolonged
operation beyond these ranges may result in a shift of sensor reading with slow recovery time.
2. Excludes hysteresis, long term drift, and certain other factors and is applicable to non-condensing environments only.
See “4.2. Relative Humidity Sensor Accuracy” for more details.
3. Drift due to aging effects at typical room conditions of 30
C and 30% to 50%. May be impacted by dust, vaporized
solvents or other contaminants, e.g., out-gassing tapes, adhesives, packaging materials, etc. See “4.9. Long Term
Drift/Aging”.
4. Response time to a step change in RH. Time for the RH output to change by 63% of the total RH change.
