Air temperature and relative humidity

Available Models

Air temperature and Relative Humidity

Analogue, digital, radio outputs

Thermohygrometer designed for severe climatic weather conditions with anti-radiation screen.
Models available with an effective natural ventilation anti-radiation screen that ensures the protection of the sensitive element from solar radiation to ensure the accuracy of the temperature reading. For best results in the case of low wind speeds and high levels of solar radiation, some models are equipped with a forced ventilation screen.
  • 4 ÷ 20 mA, RS485-Modbus RTU, Radio output versions;
  • Forced ventilation radiant screen available;
  • Replaceable sensitive element;
  • Programmable air temperature measurement range.

temperatura aria uscita diretta 01

Direct signal output

Thermohygrometer designed for conditions of strong thermal and hygrometric variations.
Accurate and reliable, these sensors are suitable for continuous meteorological measurements even in severe climatic conditions and in the presence of strong thermal and hygrometric variations. These sensors must be housed in an antiradiant shield with natural or forced ventilation. Models with Pt100 output for temperature and 0 ÷ 1 Vdc for relative humidity output 0 ÷ 1 Vdc for both temperature and relative humidity are available. A model is available that is designed for continuous conditions of high temperature and relative humidity typical of tropical climates.
  • Design and performances addessed to meteorological applcations;
  • Fast return after saturation;
  • High protection from salty and polluted air;
  • High efficiency radiant screen;
  • Optional forced ventilation radiant screen;
  • ISO17025 traceability.
