Pettersson Ultrasound Detector USB Microphones Serie 500

Pettersson M500 and M500-384 USB Ultrasound Microphones

Capture high-quality, full-spectrum recordings of bat calls directly on your smartphone, tablet, or computer with advanced acoustic monitoring technology.

The M500 and M500-384 USB microphones are versatile and compact tools that transform everyday devices into powerful ultrasound recording systems. Housed in a slim and durable aluminum enclosure, both models utilize the same high-precision electret microphone technology as the renowned D500X detector. While the M500 is optimized for Windows systems and offers a 500 kHz sampling frequency, the M500-384 stands out for its universal compatibility (Android, iOS, Windows, macOS, Linux), operating as a standard audio device that requires no custom drivers. Featuring an 8th-order anti-aliasing filter and low-noise technology, these microphones ensure the highest fidelity for recording biological signals and industrial ultrasonic emissions.
