HumiSys ™ HF - High Flow RH Generator
HumiSys HF
Fully automated RH systems with multi sensors, automatic
water supply, heated transfer line, and Windows® based
software (compatible with 64-bit Windows® operational
system) for supplying precisely controlled RH stream to the
chambers for evaluation of processes at user-defined
conditions of relative humidity and temperature.

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).
Operational Schematic of HumiSys HF
Design Features:
Two mass flow controllers (MFC) – fast response
Large range of flow range – up to 50 L/min (typical MFC ranges)
RH from 0 to 100%
Saturator temperature up to 95C for extended temperature models
One or two digital RH probes (RH and temperature data)
External temperature probe (RTD based)
Can accept additional sensors (0-5VDC)
Automatic water supply system
Heated transfer line
Models for higher pressure e.g. 20 psig are available.
Precision pressure regulator and gauge
Open design for easy interfacing with other equipment
Auto/Manual operation
USB or serial port for data transfer
Windows based software for experiment design and control.
(Our software is compatible with 64-bit Windows® system)
Very low cost
Applications:
- Controlled relative humidity source for study processes at different moisture, temperature, and pressure conditions
- Evaluation of distribution of RH and temperature gradients in chambers
- Gravimetric moisture sorption systems
- Forward flow method through filters, beds at flow rates with different humidity level
- Instrumentation measuring Water Vapor Transport Rate (WVTR)
- Maintenance of precise moisture conditions in environmental chamber under flow
- RH source for calibration and verification of relative humidity sensors
- Easy interfacing with larger analytical setups (X-Ray diffractometer, DMA, DMTA, TGA, etc.)
- Pressurized applications, typically up to 1.5 Bar (25psi) above the atmospheric pressure

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.
