As a designer of high pressure measuring systems for 38 years for the aerospace industry resulting in multiple patents. Ken spent countless hours in his library researching materials and chemical compatibility. Realizing the challenge facing design engineers in selecting appropriate materials for specific environments, he began researching material compatibility to guide product design. Kens research over a period of more than 35 years resulted in a collection of comprehensive publications for our valued clients.

What Our Customers are Saying

“I love your books. This is actually the third set I bought from your company. I was introduced to them when I was a young applications engineer. I needed to know what materials would work with what chemistries. Since I have changed jobs a couple of times, I always need to buy a new set every time since they become a valuable source of information that I and the companies I have worked for rely on.”
Ken Adrian, Product Manager, Graver Technologies


“These books are Bibles for applications engineers and consultants.”
Michael Ridey, Consultant CMR Resources


“I would like to acknowledge your organization for publishing the absolute best compatibility guides I have ever used. They are truly the best go-to references for compatibility. I use all three of your guides daily.”
Dan Purkat, Technical Specialist, GRACO INC.


“When consulting vendors they state ‘Always refer to the Compass Corrosion Guides for verification’.”
Richard Sherwin, Sr. Plant Maintenance Engineer, PRAXAIR


“Can’t wait to get my hands on your corrosion guide. We should have bought it years ago. My colleagues at our sister company US Hose Corp swear by theirs. Now I can stop nagging them to look up references for us all the time!”
