ETI

Echo Technologies Inc. (ETI) was established in 1997 as a sensor and instrumentation development company, specialising in techniques for the detection of harmful biological agents.  Its laboratory facilities are located near the Seaport District in Boston, Massachusetts. The company's initial business focus was directed toward the development of optical sensors and instrumentation for the detection of biological agents and chemical contaminants.
As well as protecting the public from the dissemination of biological and chemical warfare agents, it looked at public health threats, including new and emerging diseases, contaminated food products and poor indoor air quality. One example is the EchoSensor, a compact biological-warfare detection system, developed to monitor the presence of airborne bacterial agents.  ETI also adapted its core sensor technology for rapid detection of microbial contamination in drinking water and recreational waters. 
ETI has enjoyed collaboration with Harvard University, the University of British Columbia, Michigan Molecular Institute, University of South Carolina and the Army Research Laboratory on projects ranging from basic research to development of prototype sensor instrumentation.
