GeoSpectrum sells a number of calibration systems (see Calibration Equipment under Products) and uses even more in its own development work. If you have a need to calibrate your hydrophones, we can choose an appropriate method.
Two calibrations might be of particular interest.
1) High absolute accuracy at a single low-frequencies.
2) Portable calibration system as a function of frequency. You can either bring your acoustic system to us for calibration, or we can bring our portable system to you. Many of our calibrations are done in Bedford Basin (70 m water depth available).
