Campbell Scientific HC2S3 Temperature and Relative Humidity Probe - Manual (Page 16)

Model HC2S3 Temperature and Relative Humidity Probe
6.2 Relative Humidity Sensor
Sensor: ROTRONIC Hygromer ® IN1
Relative Humidity
Measurement Range:
0 to 100% non-condensing
RH Output Signal Range: 0 to 1 Vdc
Accuracy at 23 °C: ±0.8% RH with standard configuration
settings
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)):
≤22 s with PE filter, ≤30 s with Teflon
filter
RH Accuracy over Temperature:
The black outer jacket of the cable is Santoprene ® rubber.
This compound was chosen for its resistance to
temperature extremes, moisture, and UV degradation.
However, this jacket will support combustion in air. It is
rated as slow burning when tested according to U.L. 94
H.B. and will pass FMVSS302. Local fire codes may
preclude its use inside buildings.
