About Us

Water quality monitoring systems for wastewater, drinking water and environmental applications.

Photonic Measurements Ltd is a multi-award-winning, UK and EU-based global provider of advanced water quality measurement instrumentation, specialising in wastewater, drinking water, and environmental sectors.

The UV254 Go! is a game-changer for us. We can truly trust its readings, giving us peace of mind and the confidence that our clients can deliver optimal water quality. "

"We use it weekly to monitor our raw water. It’s been trouble free, and it gives very comparable results to the $60K Lab Analyzer that our lab counterparts use for organic characterization when we sample at similar times. We have been happy with our purchase."
