Linkam - Model RHGen -Relative Humidity Controller for Environmental Sample Control
The RHGen Relative Humidity Controller is an advanced instrument designed to precisely manage the environmental conditions for a variety of temperature stages within scientific and industrial applications. This device, compatible with Linkam's MFS, THMS600, HFS600, and LTS420 stages, empowers users with unparalleled control over relative humidity without the need for an external dry air supply. The RHGen is engineered to enhance experimental accuracy by providing stable humidity, which is crucial for testing photovoltaic materials, new battery technologies, and pharmaceuticals. The system's automatic recycling desiccant setup allows for ambient air drying, maintaining consistent humidity levels over extended periods. Furthermore, the inclusion of an Inert Gas Regulator supports the use of nitrogen or other inert gases to prevent oxidation during sensitive experiments. The RHGen stands out with its combined temperature and humidity capacitance sensor, ensuring a rapid response for maintaining conditions between 5% to 90% RH with remarkable stability.
The RHGen is now available with compatible versions of the Linkam MFS, THMS600, HFS600, LTS420 stages, and more - check with Linkam if you need an RH compatible version of our stages
The RHGen Relative Humidity Controller is designed to provide environmental sample control to Linkam’s range of temperature stages.
The RHGen provides precise control in a compact, self-contained package without requiring an external dry air supply. The RHGen makes it possible to combine temperature control with control of relative humidity within a stage. Humidity can significantly affect a material's properties; these include cosmetic surface effects to changes in a sample’s mechanical properties and chemical changes such as creating polymorphs. The RHGen has a range of applications including testing and characterising new photovoltaic materials, research into new battery technologies, and the characterisation of pharmaceuticals.
The RHGen Controller has been developed for use with RH compatible versions of Linkam’s THMS600, MFS, HFS600 and LTS420 stages’. It can also be used with any other sealed chamber with a volume up to 2000cc.
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 to control humidity for months at a time.
In addition to monitoring the humidity of the air supplied to the chamber, a sensor has also been placed inside the chamber to create a feedback loop to the controller.
For applications where oxidation is an issue, the RHGen can be supplied with the optional Inert Gas Regulator (IGR) which allows the use of nitrogen, or other inert gases, as the carrier gas.
- Stand-alone humidity generator and controller that can also be used with LINK or NEXUS software to log data from the sensor.
