Wireless Instrumentation Acoustic Monitor Field Units identify, monitor, and report fugitive emissions for compliance with local, state, and federal environmental regulatory agencies. Operating in 900 MHz, ISM license-free band, self-contained devices include acoustic sensor element and transceiver, providing 2-way communications with transmission range up to 3,000 ft. FHSS technology, error checking, and correction scheme validate that accurate data is received.
