The SPS series of moisture sorption test systems are automated devices for the determination of moisture uptake and -loss of materials.

The special features of SPS-instruments are:

• Up to 23 samples measured simultaneously
• Dynamic Vapor Sorption in an atmosphere with controlled temperature and humidity
• Excelent ratio of sample surface to sample volume at all sample sizes
• Full drift compensation using an internal reference
• Samples for external investigations can be withdrawn from a parallel position during the measuring cycle
• High precision and reproducibility with sample amounts from 
  1 milligram up to 210 g
