MeteoTemp RH+T with pressure

Make:  Barani Design    Model: MeteoTemp RH+T+P
✅ 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

3-in-1 sensor probe with the same form factor as above 2-in-1 probe. Adds Pressure to the already superb Temperature, Humidity, Dew Point and Frost Point probe without increasing power consumption to maintain the same WMO accuracy requirements for Temperature and Humidity. Features a highly reliable sealed barometric pressure transducer in the sensor head.
Also features triple lightning protection and Surge, Transient & ESD protection

Ultra-low power performance is not affected by the addition of pressure sensor. Total combined power consumption remains around 800 µA, with the addition of only 20 µA by the pressure sensor to maintain the 5x advantage over most meteorological temperature and humidity probes.

  • 3 sensors in 1 simplify your systems and extend battery life
  • Remove self-heating from your measurement data
  • Excellent value with easy re-calibration and traceability features
  • Lightning protection for ultimate reliability of air-temperature measurement
