Illinois Instruments, Inc., is celebrating its 30th year in business as one of the leading specialists and manufacturers in gas and moisture measurement.

Having been founded in 1986 to provide a manufacturing, sales, customer service and technical support function for the North, South, Central American and Canadian markets, the US-based business has hit the 30-year milestone in 2016.

Illinois Instruments initially produced its first oxygen (O2) analysers in McHenry, Illinois in 1986 before expanding into the permeation gas analyser market in 2002 due to high demand – the same year the company moved to its current US headquarters in Johnsburg.

Forming part of the brand Systech Illinois, the company now provides specialist gas analysis solutions to the process, food, pharmaceutical and packaging industries across the world.

Bryan Cummings, President of the US-based business, enthused, “Our success throughout these years is testament to our employees and partners and their continued response to industry demand. The technology we produce remains a vital component for the process, pharmaceutical and food industries.” 


Systech Illinois is the marketing name for UK-based Systech Intruments Ltd. and US-based Illinois Instruments sister companies. Each of their headquarters contains a gas analyser manufacturing facility and offices providing customer service, sales and technical support. Systech Illinois also has sales and support facilities in China and Thailand.
