Features of the relative humidity sensor*: 

*According to the data sheet of the manufacturer of the relative humidity sensor

- Range: 0 to 100% RH, -40° to 70°C (-40° to 158°F)
Exposure to conditions below -20°C (-4°F) or above 95% relative humidity may temporarily increase the maximum error of the additional 1% relative humidity sensor
- Accuracy:
±2.5 % from 10 % to 90 % (typical) to a maximum of ±3.5 % including hysteresis at 25 °C (77 °F)
Below 10 % HR and above 90 % HR ± 5 % typical
- Resolution: 0.01 per cent
- Drive: - Response time (typical, 90% of change:
Temperature:
Without solar radiation shield: 17 minutes in the air moving at 1 m/sec
With RS1/M-RSA solar radiation shield: 24 minutes in the air moving at 1 m/sec
With RS3-B solar radiation shield: N/A
Relative humidity: 
Without solar radiation shield: 30 seconds in the air moving at 1 m/sec
With RS1/M-RSA solar radiation shield: 40 seconds in the air moving at 1 m/sec
With RS3-B solar radiation shield: N/A

Recorder Features:

- Operating range: -40° to 70°C (-40° to 158°F)
