MeteoTemp RH+T

Make:  Barani Design     Model: MeteoTemp RH+T
✅ Ultra-low power even when counting-in communication power
✅ Teflon (PTFE) screw-on filter cap for easy serviceability & water repulsion
✅ Corrosion resistant and hydrophobic white sensor body
✅ Bayonet locking waterproof connector with NBR o-rings for very low & high temperatures
✅ Versatile industrial interface: MODBUS ASCII & RTU

MeteoTemp has been proven to provide one of the lowest measurement uncertainties in the market. Get the quality back into your temperature, humidity, dew point & frost point data with MeteoTemp. Eliminate self-heating effects from meteorological measurements, which with today’s sensors can reach over +0.2 °C.

Ultra-low power temperature, humidity, dew point and frost point probe for meteorological air temperature measurement. Its combined power consumption of 800 µA, is often 5x less than other meteorological temperature and humidity probes.

  • Eliminates self-heating from your measurements
  • Stable long-term temperature and humidity
  • Excellent value with easy re-calibration and traceability features
  • Lightning protection for ultimate reliability of air-temperature measurement
