The THERMASTER has been specifically designed to control and guarantee substrate surface temperature during the in vitro solar testing process, in order to comply with the various standards.

Fully suitable for PMMA substrates molded HD6 and sandblasted SB6 the metal support (with the substrate on top) is used to maintain temperature by inertia during the weighing and application stages (less than 2 minutes).

Product information

Directions for use

The THERMASTER developed by Weneos (ex HelioScreen) is a thermal chamber that maintains the substrate surface temperature for the duration of an in vitro solar test with simple operation:


  • Switch on the unit and set the desired temperature,
  • Position PMMA substrates molded (HD6) or sandblasted (SB6) on the metal supports,
  • The metal support with the substrate resting on it is used to maintain temperature by inertia during the weighing and spreading steps using the robot SPREADMASTER robot (usually in under 2 minutes),
  • The substrate is placed back on the THERMASTER (in the dark) to ensure surface temperature control during the drying stage.
