Analytical Industries Inc (Aii) design and manufacture galvanic oxygen sensors for the recreational and commercial diving user. All diving sensors are quality assured and individually tested to ensure reliability and stability with each sensor provided with pressure and test data (end of line testing for stability at ambient and 100% oxygen, 30" of water column pressure test). Manufactured in California, USA.
Many Nuvair products are available through third-party resellers, including retail stores, distributors, Amazon.com, and other e-commerce sites. For gas analyzers and replacement sensors purchased from this distribution network, the warranty period begins on the date of manufacture. However, when purchased directly from Nuvair.com, the warranty starts on the purchase date.
Why? Because many gas analyzer sensors contain chemical cells similar to battery cells, which have a limited lifespan. Nuvair takes extra care to ship only recently manufactured sensors and analyzers, ensuring the longest possible lifespan when purchased directly from Nuvair.com.
