Pollution and Process Monitoring – PPM is an independent limited company which manufactures and distributes instrumentation for water and waste-water applications. The company was founded in 1990 by a small team of highly qualified engineers that pioneered on-line TOC – Total Organic Carbon monitoring. The company has expanded over the years and now represents a number of international companies manufacturing complementary technologies. Although the UK is still the most significant market place, PPM is progressively supporting international projects supplied through UK specification and local distribution. Representation is established for the majority of mainland Europe, USA and Asia including India and China.
