This document is the instruction manual for F65 series humidity and humidity-temperature transmitters.
The Rotronic F65 Series transmitters are designed to measure humidity or a combination of humidity and temperature in manufacturing areas, clean rooms, research laboratories, and other industrial applications. The electronic circuitry is available in 2-wire loop powered or 3-wire types, providing linearized DC current or voltage outputs for transmission to remote displays or controllers. The series features the ROTRONIC HYGROMER capacitive humidity sensor, which offers exceptional durability and stability, backed by a 3-year full warranty.

The F65 series features the ROTRONIC HYGROMER capacitive humidity sensor.
Yes, specific models are designed for duct (through wall) installation.
The impedance should not exceed 500 ohms when reading the output signal.
No, operation does not require grounding, though it is recommended in low humidity environments.
