About Us - CTG have been supplying water quality sensors & systems globally for over 50 years

"Chelsea Technologies Group 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, Chelsea employs 35 engineers and scientists producing systems for the marine, maritime, environmental, defence, homeland security & process control markets. Disciplines include: mechanical design, product design, electronics, software, science & technology and manufacturing. 


Chelsea specialises 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," said Dr Brian Phillips, Managing Director. "Submariners are using  them to understand the environment they pass through, water authorities are using them to test water supplies to guard against chemical attack by terrorists. 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 sensors are being developed to 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 sensors and systems  has also come from the process control, food and automobile industries."
