Diving Sensors and Analyzers

Since we supplied our first diving oxygen sensors to the U.S. Navy in 1998, we have developed and extended our range. Today, we are proud to be the preferred supplier of O₂ sensors to some of the most reputable rebreather manufacturers throughout the world.

Our O₂ sensors are engineered specifically for use underwater at depth. Every O2 sensor is subjected to stringent quality assurance program that checks the output and stability of each 3-4 times during the manufacturing process. As a result, every rebreather sensor is qualified and its hyperoxic linearity documented prior to shipment.

With AII Diving Sensors you can Dive with confidence!

Certified Quality
A test report accompanies every rebreather oxygen sensor shipped from the factory and is traceable to each unique serial number. It is the buyers’ certification that a particular sensor has demonstrated a stable output in air (20.9%), a linear and stable output at both 100% oxygen and when pressurized to 1.6 ATM using specialized diving sensors test equipment.

Our Quality Assurance Program is certified annually and complies with ISO 9001:2008 and medical device regulations in the U.S., Europe and Canada.
