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

TurbiLux - Turbidity Fluorometer Sensor

TurbiLux is a sensitive, low cost digital IR turbidity sensor designed for compliancy with ISO 7027:1999 standard that offers the user significantly increased functionality when compared to existing turbidity sensors. TurbiLux can be deployed in a wide range of applications including flow-through systems for process monitoring and in-situ deployments in rivers, lakes and oceans. The TurbiLux has an acetal resin housing suitable for deploying ...

FastOcean - ADP Profiling System

FastOcean APD is an automous profiling system which comprises two FastOcean multi-wavelength Fast Repetition Rate fluorometers (ambient plus dark), pumped dark chamber, programmable battery pack and a PAR sensor for autonomous, in situ estimation of gross primary production. This system is smaller, lighter and more power efficient  than earlier FRRf profiling systems. This high performance system is suitable for use in a wide range of ...

FEATURED APPLICATIONS

Real-time In-situ Effluent Monitoring

The UviLux BOD Indicator enables in-situ, real-time, reporting of BOD within both natural water systems and water processing plants. The monitor detects fluorescent proteins that are inherent within sewage and slurry and provides an output in BOD equivalent units. The principle behind the measurement is the excitation of Tryptophan-like fluorescence within UV wavelength band, which has been shown to correlate with both BOD and bacterial contamination. With complete flexibility of deployment methodology, the...

Monitoring of Algal Production / Monitoring of Algae Growth

Over the past 20 years active fluorescence has been widely adopted by the scientific community, ecosystem managers and crop growers as a rapid and non-invasive method of estimating photosynthetic performance within a wide range of organisms, including phytoplankton (microalgae and cyanobacteria), biofilms, benthic autotrophs (corals, macroalgae and sea grasses) and terrestrial plants. The main rational for applying active fluorescence is that changes in key fluorescence parameters can reveal the early onset of...
