The stylish housing is well vented to provide air flow across the sensor to improve measurement accuracy. The humidity and the dew point are measured using a capacitive polymer sensor that completely recovers from 100% saturation. The humidity and dew point can have either a current or voltage output, while the optional temperature output can be a current, voltage, RTD, or thermistor. For models with current or voltage for the temperature output, the temperature range is field selectable.SPECIFICATIONS Relative Humidity Range0 to 100% RH.Temperature Range-40 to 140°F (-40 to 60°C) for thermistor and RTD sensors; -20 to 140°F (-28.9 to 60°C) for analog outputs.Dew Point Temperature Range-20 to 140°F (-28.9 to 60°C); 0 to 100°F (-17.8 to 37.8°C); 40 to 90°F (4.4 to 32.3°C); -4 to 140°F (-20 to 60°C) field selectable ranges.AccuracyRH: Model RHP-2XXX: ±2% (10 to 90% RH @ 25°C), Model RHP-3XXX: ±3% (20 to 80% RH @ 25°C), Model RHP-5XXX: ±5% (20 to 80% RH @ 25°C); Thermistor temperature sensor: ±0.36°F @ 77°F (±0.2°C @ 25°C); RTD temperature sensor: DIN Class B, ±0.54°F @ 32°F (±0.3°C @ 0°C); Analog outputs: ±0.9°F @ 77°F (±0.3°C @ 25°C).Hysteresis±1%.Repeatability±0.1% typical.Temperature LimitsOperating: -40 to 140°F (-40 to 60°C); Storage: -40 to 176°F (-40 to 80°C).Compensated Temperature Limits-4 to 140°F (-20 to 60°C).4 to 20 mA Loop Powered OptionsPower requirements: 10 to 35 VDC; Output signal: 4 to 20 mA, 2 channels for humidity/temperature models (loop powered on RH).
