HumiSys ™ HF
The HumiSys HF RH generator employs divided-flow (split-flow) technique and utilizes two mass flow controllers for fast response. In the
main mode of operation, one RH probe is used for RH control and is usually placed inside the user chamber. The second (optional) RH probe
can be placed at any user-defined location for verification of RH and temperature uniformity. In cases where RH probe cannot be installed
inside the user chamber, a miniature RH probe can be placed inside the HumiSys HF generator and the temperature of the user chamber can
be monitored by the (optional) temperature probe (RTD based).

To facilitate interfacing of the RH generator to existing setups, we
offer selections of hardware equipment and customization (often
without any additional cost) to best address the application(s).
Operational parameters, like flow, temperature, pressure, RH range,
distance between the RH generator and the test chamber, port sizes,
etc.are helpful.
