Thermohygrometer, natural ventilation - Radio output

Precise and reliable, this sensor is suitable for continuous meteorological measurements also in severe environments and in presence of steep thermal and hygrometric variations.
For outdoor application it should be coupled with a radiant screen. 

Instruments for accurate measurement of air temperature and relative humidity in severe outdoor environments. 

Highlights

  • 4 ÷ 20 mA, RS485-Modbus RTU, Radio output versions;
  • Forced ventilation radiant screen available;
  • Replaceable sensitive element;
  • Programmable air temperature measurement range.
