The Relative Humidity Module (RHM) is an environmental sample chamber to allow mechanical tests to be performed under conditions of controlled humidity, temperature, or in liquid (sample fully submerged). The typical configuration of the ASA is vertically mounted with the indenter above the sample, but other configurations are also possible depending on options installed.

The relative humidity (RH) can be controlled over the range 5 – 95% with an accuracy of 1.5%. The temperature range is from room temperature to 70°C with an accuracy 0.1°C.

For fully submerged testing without RH and temperature control, the Liquid Cell (LIC) can be used.
