Process Instruments (UK) Ltd. (Pi) is a global supplier, providing water analyser instrument solutions since 1998. With offices, a laboratory and manufacturing facilities in Burnley (UK), with subsidiaries in Ireland and France and a company representative in China, 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 analysers on the market.

Pi's Values, Vision and Mission

Pi’s Values, Vision and Mission

Recognising that no two applications are the same, Pi develops solutions to meet customer requirements and remains committed to product development and improving customer relations by delivering invaluable on-site support, excellent customer service, knowledge and expertise. Pi has been awarded the ISO 9001 quality certification, the ISO 14001 environmental certification and the BS OHSAS 18001 Occupational Health and Safety Management Systems certification. Achieving growth of on average >25% almost every year since the launch of its products, Pi has continued to invest heavily in Research & Development (accounting for >30% of overhead) so can be relied upon to always deliver the most technologically advanced systems on the market.

Many of the innovations brought to market by Pi are the result of years of collaboration with educational institutions such as The University of Manchester, The University of Lancaster and The University of Warwick. This continual product development has also led to Pi winning numerous awards over the years including the International Achievement and Editor’s Choice Award at the Red Rose Awards, the Technology Award at the Lancashire Telegraph Business Awards, and the Innovation Award at the Burnley Business Awards 2015. Pi was also regional winner of the Achievement in International Business at the British Chamber of Commerce Awards and has won the O2 Award for Innovation through Technology, a DTi SMART Award and was recipient of a DTi grant for Research & Development (NWDA). Most recently Pi has been awarded two Innovate UK Grants from the UK’s Technology Strategy Board, and the Engineering Award at the Red Rose Awards 2017.

Pi is known to make the best Water Quality Analysers on the market – so it comes as no surprise that other companies want to sell them as their own under Private Label agreements. In addition to the original design and manufacture, Pi provides all the training that their customers need. By re-selling Pi products under their own branding, Private Label customers save a fortune on their own development costs.

The CRIUS® controller has been improved in 2018 to be Water 4.0, Industry 4.0 and Internet of Things compliant and now provides even more functionality for the discerning engineer.
