The test chambers can be opened pneumatically. Its ergonomic design, in a combined cabinet/chest shape, ensures that the samples can be loaded in a very user-friendly manner. Various sample holders are available as accessories. A TFT display with function keys and full-colour touch functionality is used for the operations.
