EE071 is optimized for use in demanding OEM applications. In addition to the precise measurement of humidity (RH) and temperature (T), the EE071 calculates physical quantities such as dew point temperature, mixing ratio and absolute humidity. All measured and calculated values are available on the RS-485 interface with Modbus RTU protocol.
The RH and T sensor HCT01 is perfectly protected against dust and dirt by the E+E proprietary coating. Furthermore, all solder pads are sealed against corrosion. With the appropriate filter cap the EE071 offers outstanding long term stability even in harsh environment. The compact design with M12 connector allows for easy installation and fast replacement of the probe. With the optional Modbus configuration adapter the user can perform RH and T adjustment and set the Modbus parameters.
