TEMPERATURE
Measurement range -40 ... +60 °C (-40 ... +140 °F)
Accuracy
At +20 °C (+68 °F) ±0.3 °C (±0.54 °F)
Temperature dependence ±0.01 °C/ °C
Temperature sensor Pt1000 RTD Class F0.1 IEC 60751
CALCULATED PARAMETERS
Measurement range for dew
point temperature and wet bulb
temperature -40 ... +60 °C (-40 ... +140 °F)
Measurement range for enthalpy -40 ... 460 kJ/kg
(-10 ... +190 BTU/lb)
Accuracy of the calculated parameters should be
calculated at the actual condition based on the
relative humidity and temperature specification.
Accuracy at 20°C (68°F) and 80%RH:
Dew point ±0.9 °C (1.6 °F)
Wet bulb temperature ±0.7 °C (1.3 °F)
Enthalpy ±2kJ/kg (0.9 BTU/lb)
