Psychrometer sensor

Dry bulb and wet bulb temperature sensor

Psychrometer sensor with wet&dry bulbs and forced ventilation.

Wet bulb is closed inside a wet cotton sock from a distilled water tank. This sensor has a very good stability because it is based on a direct measurement of temperature using 1/3 DIN element and it is not sensitive to the time drift of every hygrometer element. LSI-Lastem data loggers can calculate Relative Humidity starting from wet&dry temperatures.

Psychrometer sensor


  • Wet&Dry forced ventilation temperatures sensor. Design made according to ISO7726 standard;
  • Direct calculation of the Relative Humidity and Dew Point using LSI-Lastem’s data logger according to ISO7726 standard;
  • 2% accuracy assured over the whole range (0-100%) and wide operative temperature (0÷60°C);
  • High accuracy Pt100 1/3 DIN B sensitive elements;
  • Forced ventilation on the sensitive elements: >2 m/s;
  • Long term stability and robust principle. Applications in polluted/salty air even near the saturation with high temperatures;
  • Internal ISO17025 accreditated calibration laboratory.
