Working at Chelsea Technologies Ltd

Chelsea Technologies designs and manufactures ingenious environmental monitoring technology to make the world safer, cleaner and smarter.

Across shipping, marine science, water quality, defence and industrial process control, our best-in-class sensors and systems are trusted for the sensitivity, accuracy, reliability and sophistication. We’ve built our unrivalled specialist expertise over 50 years, and we apply this with new rigor to every engineering challenge our clients set us.

Our pioneering technology is helping to gauge shipping emissions, explore the oceans, create healthier fisheries, optimize crop spraying, improve production efficiency, even monitor microplastics and climate change.

The power of pure inspiration from Chelsea Technologies. 

Chelsea Technologies Ltd has over 50 years experience in the design and manufacture of a range of sensors and systems to monitor various parameters of water. Based in West Molesey, Surrey, we now employ over 40 engineers and scientists producing systems for the maritime, marine science, water environmental, defence & process control markets. Disciplines include: mechanical design, product design, electronics, software, science & technology and manufacturing.

We specialis in optical, acoustic and physical sensors measuring temperature, conductivity, hydrocarbons, fluorescence, water clarity and primary productivity.

Our customers have been using our high quality sensors and systems in a wide range of applications. Submariners are using them to understand the environment they pass through, water authorities are using them to test water supplies. Scientists globally monitor changes in oceanic algae and the effects on climate change. Shipping companies have installed our state-of- the-art in-line sensors to monitor exhaust gas cleaning systems and assess the real time performance of ballast water treatment systems. Our highly sensitive hydrocarbon fluorometers are used in glider based systems to provide persistent, real time monitoring of hydrocarbon levels around drilling and production platforms. Demand for the Chelsea Technologies sensors and systems has also come from the process control, food and automobile industries.
