Accuracy*
(including hysteresis, non-linearity
and repeatability, traceable to
international standards,
administrated by NIST, PTB, BEV)
–15 to 40 °C: ≤90% RH ± (1.3 + 0.003 • RH reading) % RH
–15 to 40 °C: >90% RH ± 2.3% RH
–25 to 60 °C: ± (1.4 + 0.01 • RH reading) % RH
–40 to 60 °C: ± (1.5 + 0.015 • RH reading) % RH
Typical Long-Term Stability: <1% RH per year
Sensor Time Constant [63% of a
35 to 80% RH step change
(1 m/s air flow at sensor)]
Standard PE Filter:
≤
22 s
Optional Teflon Filter: ≤ 30 s
* The accuracy statement includes the uncertainty of the factory calibration with an
enhancement factor k=2 (2-times standard deviation).
The accuracy was calculated in accordance with EA-4/02 and with regard to GUM
(Guide to the Expression of Uncertainty in Measurement).
