How AMI sets ourselves apart

Extensive system features

Whether it’s measuring moisture and oxygen purity, or even adding additional oxygen from an external charging source, AMI’s Oxygen Quality Tester provides an unrivaled array of capabilities. And as with many of our offerings, customers have the capability to add custom tests and features as needed. 

Advanced safety equipment

The AMI Oxygen Quality Tester sets itself apart from other oxygen quality test systems. Not just because of what it can do, but also because of what it can prevent. Oxygen Concentration Monitors come standard on each tester and are designed to protect the operator during the testing and filling operations. This allows aerospace companies to make all necessary measurements to reliably test oxygen quality.

Exceptional quality

Our team puts its heart and soul into each project we perform. Utilizing over 30 years of experience in business, our team uses a set of proven processes for each phase of the project. From start to finish, we make it a priority to use only top-quality materials and technology. And once we design and assemble the product for installation, we initiate an extensive quality assurance process that ensures your tester performs correctly for years to come.

Key Specialties

Breaking down AMI’s Oxygen Quality Tester

Primary Function

The primary function of an AMI Oxygen Quality Tester is to perform moisture and oxygen purity measurements for various types and sizes of aviation oxygen cylinders.  All these measurements are performed according to the specifications of the related CMMs.  The tester features a four-stage hygrometer sensor to measure the humidity, temperature, and pressure of the oxygen inside the cylinder under test. A water chiller can be added as an option to shift the measurement range if desired. The purity of the oxygen is measured by an oxygen analyzer.


The AMI’s Oxygen Quality Tester also features the capability to connect the cylinder under test to external charging equipment. This allows for the addition of extra oxygen as needed. This feature comes standard, with the capability of adding custom options upon request.
