Key features

  • New class of Weather Sensor with high-quality aluminum housing
  • Traceable accuracy, due to detailed calibration certificates, performed by an accredited laboratory for every sensor
  • Modular architecture, which allows easy maintenance and calibration possibilities for every single sensor
  • Drift-free sensing technologies
  • Excellent survivability under extreme conditions
  • Full-metal construction with ventilated air temperature / humidity measurements
  • WiFi enabled

Accuracy in Detail:

  • Temperature better than +/- 0.1°C
  • Relative Humidity better than +/- 2%
  • Air Pressure better than +/- 0.1 hPa

Relative humidity is measured by means of a heated capacitive sensor element; a precision PT100 measuring element is used to measure air temperature. A resonant pressure transducer is employed for precise pressure measurement.
