HygroFlex8 - HF8 - transmitter
The HF8 is a multi-function transmitter designed to meet the requirements of applications requiring multiple instruments with one self contained instrument. The HF8 has an extensive set of optional functions and settings that can be configured and enabled with the ROTRONIC HW4 software after connecting the HF8 to a PC.
Applications
Measures relative humidity, temperature and all calculated (psychrometric) parameters in the fields of HVAC, industry and pharmaceuticals.
