This is an extremely valuable book on O2 handling, O2 cleaning, and mixing systems. A great how to book for hands on people interested in gas blending and setting up their own mixing setup. This is one of the best books, I personally have read on the subject.

A good reference book on blending. Covers analyzers and blending systems.

This is the textbook we use for our Gas Blender / O2 technician class. Probably the best book in our library on the subject of mixing. The charts in this book are invaluable, covers Nitrox and Trimix fills from empty. Covers calculations for remixing gas, O2 cleaning and service and handling O2.

Specifically written for people involved in mixed gas diving with three objectives: 1) To direct you in the safe methods of blending Enriched Air Nitrox (EANx); 2) To inform you as to what types of blending systems are currently available; and 3) To provide the best return on investment for your situation. As more divers understand the benefits of using nitrox, the need for a ready supply of the gas mix increases. This is good news for diving supply facilities.

This is an interesting guide on how to build your own Haskel. Personally I think this is one area where saving money is a BAD idea, but it does have some use full info on O2 cleaning. Personally I would use this book as a good primer on how booster pumps work and avoid trying to build one yourself.
