V-Gen Mode 1 and Model 2 RH Generators utilize the fundamental two-temperature technique above 0 Celsius dew-point generation mode and divided flow technique for low values of RH generation below the dew point of 0 C.

​Two temperature controllers, that can be controlled manually or remotely,  are used for achieving the dew point generation mode. Internal or external RH probe is necessary for feedback purposes to achieve low RH spectrum generation and control.
​
​Various flow rates can be set using an easily exchangeable rotameter unit, typical flow ranges 50, 100, 240, or 500 mL/min.
For customized units, larger flow rates like 1 or 2 L/min are possible but at reduced upper range of dew points.
​For applications requiring working with RH under vacuum or pressure, customized versions are available.

V-Gen Model 1-Dew Point Generator​ 
​The V-Gen Model 1 features Manual operation mode only. ​

​V-Gen Model 1 is designed for variety of RH needs, fast setup, long term continuous operation with no user intervention, and cost effective applications. Recommended for applications where manual control is preferred or for OEM customers who prefer implementation of their own direct control over I/O (TTL) and analog lines (0-5VDC).

V-Gen Model 2-Dew Point / RH Generator​ 
​The V-Gen Model 2 is fully automated Dew Point / RH
generator and its newly redesigned version features enhanced electronics, software, and performance.

V-Gen Model 2

    ​Features:

• Two-temperature and divided-flow techniques
• Automatic water supply system maintaining constant water level, with external water tank
• Heated transfer hose, typically about 1.5 m (5ft) length, can be customized, 24 V DC operation for safety
• Stable and precise dew points from 0 to 90 C
• Negative dew points are generated by the divided-flow method
• RH from 0 to 100% from 0 to 90 C (flow range dependent)
• Designed to address most RH needs
• Option-rich, configurable, easy integration with other equipment
• Multi mode of operation and software control
• Ability to accept external sensors: RTD, RH probe, Dew Point Analyzer...
• RH probe can be installed inside V-Gen or at user sample chamber
• Customized versions for output pressures up to 50 psig

V-Gen Model 2​ is designed for easy interfacing with other analytical instruments that would benefit from measurements in  RH controlled atmosphere. Internal and external temperature probes (RTD1 and RTD2), RH probe for relative humidity and temperature measurements,  microcontroller board, ancillary electronics, firmware software featuring simple command language and digital protocol for transferring RH and temperature data from RH probes (16 bit resolution) are added to form the fully automated RH generator in addition to still having the capabilities of the Manual Mode.

Recommended for fully automated  applications and calibrations purposes.
Automatic operation via sophisticated PC software (any Windows OS) for experiment design and control.
Any master controller can use the command language to control the generator via serial port.
