Proteus Instruments
The Proteus is the world’s first, scientifically proven, award winning, real-time sensor that can measure a wide range of water quality, environmental and industrial applications. A multiprobe that measures your choice of parameter, all in one package, that can deliver data in the toughest field conditions. The Proteus range of multiparameter sensors represents a step change in real-time monitoring of dissolved organic matter. The state-of-the-art monitoring platform incorporates the latest technology to provide accurate, reliable and minimal maintenance monitoring of Biochemical Oxygen Demand (BOD) and Dissolved Organic Carbon (DOC). The probe provides real-time data on the levels of dissolved oxygen, organic carbon and detects bacterial contamination, to provide continuous monitoring of the health of water systems, their ability to support aquatic life, and their safety for leisure use. The Proteus multiprobe is manufactured and distributed by Proteus Instruments, a trading division of RS Hydro Ltd. The Proteus is changing the way water quality is monitored. It has the same level of accuracy as laboratory testing, and delivers data in real-time, so can provide continuous monitoring. It is also robust and low-maintenance, meaning it can operate in even the harshest and most remote environments. The probe has already been installed in locations around the world including the River Ganges, the Chicago River, and Swansea Docks, Proteus is already working with water companies, environmental regulators, and NGOs including the World Bank, is confident of a high demand for this new technology. The team is extremely proud to be awarded the Queen’s Awards for Enterprise: Innovation. 1 of only 51 organisations in the UK to receive this award, which is the highest accolade for any UK business.
