Technology investment firm Battery Ventures has grown its portfolio of process-measurement and analysis companies after acquiring Analytical Industries Inc. (AII).

AII, an electrochemical oxygen (O2) sensor and gas-analysis product manufacturer based in California, will join Battery’s already extensive portfolio of analysis companies, including Michell Instruments, which the company acquired in October 2016.

Founded in 1994, AII manufactures O2 sensors and analysers for process-control and safety applications across industrial, medical and diving markets.

It is understood that AII’s electrochemical-sensing technology and US market presence strongly complements Michell’s existing product offering and geographic reach, as solutions from both companies are used across the globe to optimise production and operation efficiency.

”The combination of AII with Michell will enable us to accelerate new product development”

Adam Markin, CEO of PST

According to a statement from the company, Battery’s combination of Michell and AII aims to create a “leading platform of comprehensive process-sensing technologies with global reach.”

Adam Markin, CEO of Process Sensing Technologies (PST), Battery’s platform in the process-measurement market, underlined, “The combination of AII with Michell will enable us to accelerate new product development, deepen our technical expertise, expand our geographical presence and broaden our product and service offerings.”

Financial details were not disclosed. AII will continue to work from its manufacturing site in Pomona, California.
