High Speed Production Hydrophone Calibrator

Hydrophones that are used well below their first resonance and are small compared to a wavelength are best calibrated in air at a low frequency. GeoSpectrum’s hydrophone calibrator combines high accuracy with a high throughput, making it ideal for high-volume production. One operator can calibrate 200 hydrophones per hour; two operators can calibrate 400 hydrophones per hour.
