Overview
Analytical Industries Inc. (Aii) designs and manufactures galvanic oxygen sensors for both recreational and commercial divers.
Each sensor undergoes thorough quality assurance and individual testing to guarantee its reliability and stability. We provide pressure and test data with every sensor, including end-of-line testing for stability at ambient conditions and 100% oxygen, as well as a 30" water column pressure test.
Aii ship only "fresh" diving sensors directly from our factory in California, and are typically available for shipment within 24 hours.
Aii scuba and rebreather diving sensors are manufactured in the USA.

A galvanic oxygen sensor is a device used to measure the concentration of oxygen in a gas mixture. It is commonly used in diving equipment to ensure the safety and well-being of divers by monitoring oxygen levels.
They are crucial for monitoring the oxygen concentration in rebreathers, ensuring divers receive the correct amount of oxygen. Accurate and reliable sensors are essential to avoid health risks and ensure the proper functioning of life-sustaining equipment.
Diving O2 sensors are used to monitor the oxygen concentration within diving rebreathers, ensuring that divers receive the correct amount of oxygen while underwater.
The core mechanism involves oxygen diffusing through a sensing membrane to the cathode, where it undergoes a reduction reaction. The resulting flow of electrons from the anode to the cathode generates a current proportional to the oxygen concentration.
Due to the extreme pressures and challenging conditions underwater, stable and accurate sensors are essential to prevent equipment malfunction, which could jeopardize a diver's life.
Their ability to produce a current that is proportional and linear to the partial pressure of oxygen in the sample gas simplifies the interpretation of oxygen levels, making them highly reliable for diving applications.
Quality control includes testing output in air, linearity to 100% O2, output at 100% O2, stability at 100% O2, extensive leak tests, and pressure pot testing at elevated pressures to simulate actual conditions.
PST's diving O2 sensors can replace those in IT Gambert, Maxtec, Teledyne, and Vandagraph equipment, making them versatile for various diving systems. The sensors are compatible with various diving equipment, including rebreathers, Nitrox and helium oxygen analyzers, and CO analyzers.
Quality control testing includes: Output testing in air and at 100% O2, Linearity testing to 100% O2, Stability testing at 100% O2, Leak tests to confirm seal integrity, Pressure pot testing at elevated pressures to simulate actual diving conditions
