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.
