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.
