The Linkam Humidity Controller, RH95, has been designed to add additional environment control for your sample. With the RH95 is it now possible to combine temperature control with control of the relative humidity within the stage. Humidity can have a significant effect on the properties of a material. These include cosmetic surface effects to changes in a sample’s mechanical properties and chemical changes such as creating polymorphs. The RH95 has found many applications areas ranging from testing and characterizing new photovoltaic materials, research into new battery technologies to the characterisation of pharmaceuticals.

The RH95 controller has been developed for use with the THMS600, TST350, HFS600 and LTS420 stages, as well as any other sealed chamber with a volume up to 2000cc from 5 to 90%.

Unlike other humidity systems, no costly dry air supply is required.  Ambient air is dried through a specially designed automatic recycling desiccant system. The system can be left controlling humidity for months at a time.

Rather than simply monitoring the humidity of the air supplied to the chamber we also place a sensor inside the chamber to create a feedback loop to the controller.

For applications where oxidation is an issue, the RH95 can be supplied with the optional Inert Gas Regulator. This then allows the use of Nitrogen as the carrier gas.
