PART 4 SPECIFICATIONS
SENSOR SPECIFICATIONS
Relative Humidity (RH)
Accuracy/Range:
Non-­linearity: ±3%
Hysteresis: ±1% RH
Response Time:
4 sec (63% slowly moving air)
Repeatability: ±0.1%
Resolution: 0.03%, 12bit
NOTE: Reconditioning of the probe may
be necessary if the probe is stored for a
period of time in a harsh environment
(e.g. high humidity or exposure to
chemicals). To recondition the probe:
heat probe for 1 day at 100°C to return
it to calibration conditions.
