GP Calibrator
The GP Calibrator is a battery operated field calibrator designed for GP hydrophone series. Easy to carry is ideal to perform field calibrations just before underwater noise measurements. This calibrator is provided with relative custom software to download and display data and graphs resulting from the acoustic and electronic calibrations.
Communication is achieved serially via USB-A port on the field calibrator. Using custom adaptors it can be even used with different types of hydrophones.
Features
Easy to use and configure, allows different types of calibrations:
• Acoustic (fixed or sweep frequency from 100Hz to 700Hz)
• Electronic (fixed or sweep frequency from 3Hz to 200 kHz)
• Complete (Acoustic + Electronic)
