Understand the systems behind every fill, manage oxygen safely, and take control of gas production
The TDI Nitrox Gas Blender course provides the training required to competently and safely blend nitrox gases for diving operations.
This program focuses on the correct handling of oxygen, blending techniques, and the systems used to produce enriched air nitrox. Divers and dive professionals gain a clear understanding of how gas is produced, analysed, and delivered safely for recreational diving.
At N9BO℠, this course is positioned as operational knowledge — giving you direct control over one of the most critical components of diving: breathing gas.
This course is for divers, dive professionals, and shop staff who want to understand and safely perform nitrox gas blending operations.
No. This is a non-diving course focused on gas production, so it can be taken by non-divers involved in dive operations.
You will learn blending theory and then perform practical gas blending, including producing and analysing multiple nitrox mixes under instructor supervision.
You must successfully blend and analyse multiple nitrox cylinders (minimum five) to demonstrate competency.
You will be qualified to blend nitrox gases independently for recreational diving operations, within the limits of your training and local regulations.
Send us your background and goals. Whether you’re supporting a dive operation or expanding your technical knowledge, we’ll train you to blend safely and accurately.
Take your operational knowledge to the professional level and start teaching nitrox blending. Delivered by a TDI Instructor Trainer, this pathway builds the competence and instructional ability required to train others in safe gas production.
