Description

The Evvos RHTP probe combines meteorological grade sensors for air temperature, relative humidity, and barometric pressure measurements. It is designed to provide high-quality environmental data, real-time measurements, and calculation of multiple derivative parameters. The RHTPCO2 version of the probe includes an additional measurement of CO2-percentage (in air) compensated for relative humidity and air temperature.
It is compatible with OneSense Pulse and Voltage and OneSense Environment and Agriculture as well as many other telemetry transmitters or dataloggers supporting SDI-12 or Modbus/RS-485 interface.
