Vaisala HMP3 - Figure 36 HMP8 Humidity Measurement Accuracy as a Function of Temperature; Figure 37 HMP8 Temperature Measurement Accuracy over Full Range

Property Description/value
Factory calibration uncertainty
2)
±0.1 °C (±0.18 °F) at +23 °C (+73.4 °F)
Sensor Pt100 RTD Class F0.1 IEC 60751
1) Defined against calibration reference. Including non-linearity, hysteresis, and repeatability.
2) Defined as ±2 standard deviation limits. Small variations possible; see calibration certificate.
3) Chemical purge feature available with this sensor
4) Exposing temperature sensor to temperatures outside −20 … +150 °C (−4 … +302 °F) may
cause permanent additional deviation of ±0.1 °C (0.18 °F)
