Leaders in Water Analysers

Since 1998,
Operating in the UK.

Process Instruments (UK) Ltd. (Pi) is a global supplier, providing water analyser instrument solutions since 1998. With offices, a laboratory and new 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.

2023 is shaping up to be another big year for Pi

about Pi

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.

Ever growing, ever adapting, ever improving. With numerous product developments continually in the pipeline it is safe to say that Pi will always be leading the market, you just might not know it’s us!

The team at Pi is looking forward to continuing to work closely with its customers for everyone’s success in 2022.”
