Are you looking for the smallest chambers possible to get your testing done? Still need all the capabilities of larger chambers, though? This is the model series for you! Available in two sizes, the smaller models are the smallest humidity chambers in the world!

Easy to install and own:

  • The SU/SH models are small enough be placed underneath a benchtop or on top.
  • Designed for integration with other test equipment to make a complete test stand.
  • The smaller models run on standard 115V power enabling easy installation anywhere.
