The AR125 is a professional quality ultrasonic receiver that is designed for ultrasonic recording and acoustic analysis.  It employs a directional, wide bandwidth ultrasonic element along with ultrasonic to digital conversion technology to produce a   high quality, digitally sampled, acoustic stream that is injected directly into a laptop or lab computer for recording, and analysis.

The AR125 has a 125KHz frequency range and an outstanding 90dB dynamic range.  The combination of features and performance put the AR125 at the top of it’s class.

The AR125 is specifically designed for applications such as bat recording and vocalization analysis where directivity and a wide ultrasonic frequency range are desired.  It employs low noise circuitry along with 16-bit digital converters to achieve high sensitivity along with a large dynamic range.  It is sensitive enough to detect the faintest sound a human can hear (0 dB SPL) and it is capable of detecting bats at distances up to several hundred feet.
