Sample photo caption.
This project was first designed to upgrade a salt spray chamber on Michigan Technological Universities campus. The project has been expanded to upload all designs of the salt spay chamber to open source design.

Project goals

  1. Plan upgrades
  2. Execute Upgrades
  3. Make BOM and instructions for entire chamber
  4. Profit

Next steps

Publish detailed instructions.


This salt spray chamber would save approximately $19,000 from our first rough estimates. Our current modifications now save $475 assuming that just 4 sample racks are needed. These modifications can easily be put into most chambers with only small changes needed. This chamber has no loss in quality, and currently complies with all ASTM standards.
