Process Instruments (UK) Ltd. (Pi) is a global supplier, providing water analyzer instrument solutions since 1998. With offices, a laboratory and new manufacturing facilities in Burnley (UK), Pi has a growing reputation for innovation with customers in over 50 countries, across 6 continents. A major part of Pi’s business is through Private Label/OEM agreements, so the name ‘Process Instruments’ is not as widely known as many of our competitors. Instead of focusing on building a brand name we instead aim to provide our customers with the most reliable, flexible, and arguably the best water quality analyzers on the market.
