HumiSys™XR (Extended Range) is a versatile water vapor generator designed for variety of custom
applications requiring relatively low flow rates and extended relative humidity (RH) range regulation in the sub ambient
temperatures region. The modular design of the system, ability to work in different sensors and hardware configurations,
and versatile PC software allow for easy integration with other analytical setups....visit RH generator page

HumiSys™ MF Relative Humidity Generator is medium flow rates
version of the HumiSys HF (High FLow) RH Generator. Peltier based cooling system allows for enhancing low RH
spectrum, especially for ambient temperatures (and below) applications that require humified stream of low relative
humidity. Custom RH requirements can be easily adopted. Designed for easy interfacing with other analytical equipment
where higher flow rates are needed then in the HumiSys LF (Low Flow) or V-gen RH Generators.
HumiSys™ HF Relative Humidity Generator for high flow rates is a mass flow
controller based, high flow (up to 50 L/min), high temperature, and multi-sensor relative humidity generation system. Fast
response, wide flow range, fully automatic and manual operation, and easy integration with a larger analytical setup make it
ideally suited as a valuable R&D tool for a wide variety of applications requiring an accurate and stable source of water
vapor. Modular and "open architecture" design allows for customization to address high pressures operation and other
V-Gen™ Dew Point/RH Generator - auto/manual
Designed for easy interfacing with other equipment and can accept external sensors, like RTD, RH probe, or Dew Point
Analyzer for relative humidity measurements. Microcontroller board, ancillary electronics, firmware software featuring
simple command language and digital protocol for transferring RH and temperature data from Rotronic HygroClip probes
(16 bit resolution) are added to model 1.
Recommended for fully automated applications and calibrations purposes: automatic operation via sophisticated PC
software for experiment design and control, any master controller can use the command language to control the generator
via serial port, versions with up to 50 psig output pressure available... learn more
