Infiltec INFRA20 infrasound Monitor
The Infiltec Model INFRA20 infrasound monitor is designed to record, display and analyze infrasound below the human hearing range in the 0.05 Hz to 20 Hz range. Infrasound is produced by wind turbines, helicopters, meteors, avalanches, volcanoes, large animals like elephants, etc. The INFRA20 is designed to provide infrasound monitoring for lab, home, school and field use in a compact, portable, and rugged package that is less expensive and easier to use than conventional designs. The INFRA20 does not require any power supply or assembly or enclosure or adustment; including alignment, damping, zeroing, etc. The INFRA20 works with the standard AmaSeis Windows based software, and with the new jAmaSeis software for Windows, Linux and Mac OS.
