Chelsea Technologies Group (CTG) provides multi parameter water sensor for the environmental monitoring (both oceanographic and inland water), contamination monitoring and process control markets. Satisfying the needs of both the civil and military markets CTG specialises in technologies ranging from optical and acoustic sensors to comprehensive environmental and process monitoring systems. For monitoring of algae loading at abstraction points to Water Treatment Works (to protect and maximize longevity of filters used within the works): In situ fluorometers UniLux, Trilux algae monitor would be suitable. For protection of water supplies against accidental or deliberate contamination: FastGuard Water contamination detection system and UviLux Hydrocarbon fluorometer would be ideal. For detection of effluent levels, Biological Oxygen Demand (BOD) tracking, Combined Sewage Overflow / fish kill events and Grey Water / Black Water cross-over: UviLux Effluent Monitor

About Us

Image

A team of engineers and scientists are engaged in the design and manufacture of a range of sensors and systems for the marine, environmental, defence, homeland security, industrial process control and life science markets.  

For over 50 years, 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 to guard against chemical attack by terrorists. Scientists are using our sensors to monitor oceanic algae to tackle climate change and shipping companies have installed state of the art in-line sensors to monitor their exhaust gas cleaning systems and ballast water in order to prevent contamination of seas. Oil companies are using our sensors to detect subsea pipeline leaks and monitor oil spills. Demand for the Chelsea sensors and systems  has also come from the food and automobile industries.

FEATURED PRODUCTS

FastFlow - Fast Repetition Rate Fluorometer

The new Chelsea FastFlow Fast Repetition Rate fluorometer has been designed to monitor in real-time the ‘health’ of algae and is ideally suited for toxicant detection and bloom prediction. It gives the best indication of the water quality and can give early warning of toxic blooms.

GlowTracka - Bioluminescence Sensors

GLOWtracka is a submersible bioluminescence sensor which monitors the visible emissions from bioluminescent organisms in seawater. It is ideally suited to measure bioluminescence for toxic blooms and biomass studies to continental shelf depths (200 metres). GLOWtracka is designed to be moored, profiled (with pumped systems) or deployed in towed vehicles.

FEATURED APPLICATIONS

Water Contamination Detection

Security of water assets is becoming an increasingly major issue that demands immediate and robust alarms for potential contamination. In addition to this, natural growth of algae is a common problem for water asset managers, the results of which can increase maintenance costs of water processing plants as well as directly effecting water taste. The CTG FastGuard fast repetition rate fluorometer analyses information on the physiological state of the algae it monitors within an in-line flow system. A number of...

Turbidity Monitoring

The monitoring of Turbidity is key requirement of the water industry in both water supply and water recovery systems. Within the water supply process, monitoring of turbidity allows operators to assess the efficiency of filters for particulate removal through the process. Similarly, with water recovery (Waste Water Treatment Works), the measurement of turbidity is a key parameter to track the removal of particulate through the process. CTG can provide turbidity measurements with the UniLux sensor, or provides...
