Linkam RHGen Humidity Controller
The RHGen Relative Humidity Controller is designed to provide environmental sample control to the range of Linkam stages. It allows precise control of water vapor in the environment around a sample without the need for an external dry air supply.
The smallest change in RH% can have huge implications on the characteristics of a sample and how it behaves. When combined with a Linkam stage, or other sealed chambers, the RHGen can be used to control the RH% between 5%-90% at temperatures from ambient to 85°C (dependent on device).
Unlike many other humidity systems, the feedback sensor is located close to the sample block, ensuring accurate humidity control. The RHGen can be combined with light microscopy, Raman, FT-IR and X-ray to further characterize samples.
The RHGen controller is compatible with a wide range of Linkam stages, as well as third-party devices with sealed chambers. It is supplied with a small sealed chamber as standard, which can be used with humidity validation samples.
The system contains a specially designed, automated recycling desiccant system which, combined with the ability to top up the water even during a run, allows the system to provide humidity control for months at a time.
The RHGen is now available with compatible versions of the Linkam MFS, THMS600, HFS600, LTS420 stages, and more. Contact us if you need an RH compatible version of our stages.

INTEGRATED DESICCANT SYSTEM Ambient air is dried through a specially designed automatic desiccant recycling system which provides humidity control for months at a time without the need for a costly dry air supply.
SMART COMPACT DESIGN The small size of the controller conserves vital benchtop space and provides a neat compact humidity system. Magnetic mounting of the bottle and front panel enable easy water changing., even during an experiment
SENSOR INSIDE THE SAMPLE CHAMBER A sensor is mounted inside the chamber to create a feedback loop to the controller ensuring precise reporting and control of RH between 5%-90% at temperatures from ambient to 85°C (dependent on stage).
MULTI-SYSTEM COMPATIBILITY Humidity-compatible versions of Linkam’s THMS600, LTS420 and MFS stages are available, along with support for other sealed chambers.
INERT GAS SUPPORT The optional Inert Gas Regulator (IGR) allows inert gases such as Nitrogen and Argon to be used as a carrier gas with the RHGen.
VALIDATION A variety of certified salt solutions are available from Linkam to accurately validate the humidity sensors.
