Product Introduction

Combined sensor for measuring air temperature and humidity, accurate and reliable, compact and sturdy, made of aluminum alloy with anodized to protect against salt air and oxidizing agents. Sensor manufactured according to standard WMO (World Meteorological Organization) Annex.8 for environmental monitoring. Very fast response (<10s). Easy to install and to interface to any datalogger. Available with Accredia certification, with different electrical outputs and with forced ventilation.

  • Accurated and reliable Air Humidity & Temperature Sensor
  • Measure with high precision capacity and RTD Pt100
  • Compact and light design in aluminium for hot and cold climates
  • According to WMO standards and to EN 15518-3:2011
  • Available with forced ventilation

UTAV Thermoigrometric sensor with fan is also available
