TDI Nitrox Gas Blender Course

Gas Blending · Fill the Tanks · No Diving Required

Every nitrox fill starts with someone who knows how to blend it safely. The TDI Nitrox Gas Blender course teaches you exactly that: how to mix enriched air correctly, handle oxygen without cutting corners, and analyze every fill before it goes out the door. It's a classroom and hands-on course with no diving involved, built for dive shop staff and for divers who want to understand what's really happening at the fill station. Finish it and you're qualified to blend nitrox on your own, without an instructor looking over your shoulder.

Are there any dives?
No. This is a classroom and hands-on fill-station course. You'll do TDI eLearning for the knowledge and practical training with an instructor on real blending and analysis equipment, but there's no in-water component.
What will I actually learn?
How to blend enriched air across the common systems, partial pressure blending and the math, continuous blending, de-nitrogenated air, and pre-mix, plus oxygen safety, oxygen fire prevention, oxygen system design, and how to analyze every mix with an oxygen analyzer.
What can I do once I'm certified?
Once you complete the course, you're qualified to blend nitrox gases on your own, without the direct supervision of an instructor. It's the certification dive shops look for in the people running their fill station.
Do I need my own equipment?
No. You'll train on the shop's blending and analysis equipment. There's no dive gear to bring, since there's no diving involved.
Is this the same as the diving nitrox course?
No. The diving nitrox courses certify you to dive enriched air. This one certifies you to blend it. Many people hold both, but they're separate certifications with different goals.
