Fast Repetition Rate Fluorimeter

Biological Aerosol Threat Warning Detector

Current water monitoring systems are often very expensive and complicated to install and maintain. Chelsea Technologies developed an alternative technology, the Fast Repetition Rate Fluorimeter II (FRRF II) that monitors chemical contamination in water supplies in near real time by measuring the bio-fluorescence of naturally-occurring algae, whose fluorescence changes significantly in contaminated water. The FRRF II automatically monitors these algae and can quickly alert operators when contamination rises to unsafe levels. Initial tests show that FRRF II can identify the presence of some common toxic industrial chemicals and chemical warfare agents in water. The system is available in designs for both laboratory use as well as community water treatment systems, and is being developed for other uses related to water protection. For community systems, the installation cost is one-fourth that of current systems and the cost for upkeep is minimal. For additional information please fill out the Contact Information Form.
