Analytical Industries Inc. is part of the Process Sensing Technologies (PST) group and is based in Pomona, California. The company was founded by three engineers with experience in oxygen sensing technology who wanted to create a new range of sensors with broad measurement ranges and long useful lives.

Analytical Industries Inc. uses electrochemical processes for their oxygen analyzers. They have also developed an unique system to drain liquids from samples which may have entrained liquid. This option is available on a range of their oxygen and hydrogen sulphide analyzers. AII analyzers can also work with many competing brands’ sensors, which comes in handy at replacement time.

At Cross, our team works with a number of providers such as Analytical Industries to offer a market-leading variety of products and solutions. This ensures you have the options you need working with one vendor, Cross. Keep your project simplified, yet find the best solutions from the best providers.  For more information about AII’s oxygen analyzers, contact a Cross team member!
