HyCAD™ Advanced Hybrid Chemical Detection System

Avir, LLC designed and built the HyCAD™, a hybrid detection system for building ventilation protection and other fixed security applications that combines an optical sensor (the TOVA™, a totally optical vapor analyzer designed by Avir) and a COTS point sensor. This unique detection system, which uses two methods to detect chemical warfare agents and toxic industrial chemicals (TICs), provides improved reliability, response time, and accuracy. The system is low-cost, robust, sensitive to a large number of chemicals, and can be trained to detect new chemicals. Existing detectors or combinations thereof currently cannot provide the simultaneous protection against lowlevel exposures and gross contamination at an equally low cost. The HyCAD has undergone live TIC testing and environmental testing. Extended field-testing in select buildings is ongoing. Additional information is available at http://www.avirsensors.com.
