About Us

Over the past 53 years Partech Instruments have developed a worldwide client base thanks to our premium products, pragmatic approach and unparalleled level of customer service.

Since Roger Parker created Partech (Electronics) Ltd in 1964, we’ve certainly gone from strength to strength, with national and international accreditation alongside affiliation from leading bodies confirming our place on the world stage of wastewater measurement.

We may be 53 years old, but we have no intentions of slowing down and are certainly looking forward to the next half-century!

Our aims are simple: to provide unrivaled customer support with first-rate, tailored products combining ease of use and cost effectiveness. Our track record with over half a century of successful trading is proof that we are premium and just as importantly, people-focused.

Our reputation for service, support and specialist solutions means we’re so much more than just a name, we’re at the forefront of our industry.
