U30 Detector


A detector for professional studies of ultrasound

U30med
    •    sensitive broadband microphone
    •    detects up to 200 kHz
    •    precise digital frequency indication
    •    buffered microphone output for signal analysis
    •    replaceable microphone capsules

The U30 Bat Detector is a high-sensitivity detector with a miniature ultra-low-noise microphone, which can be operated more than 10 m away from the detector. The Detector has 2 detection systems - tuned (15-200 kHz) and a broadband frequency-division system with 3 selectable divide-by-N ratios. An efficient power management system enables operation for up to 25 hours from a pair of AA cells. The U30 Detector has a high-frequency response extending beyond 200 kHz, making it ideal for 'professional' study of animal sonar.

THIS DETECTOR IS NO LONGER MANUFACTURED, BUT PLEASE CONTACT US ABOUT REPAIRS & SERVICING.
