A measurement facility for reproduction of the unit of sound pressure in water at frequencies of 1–500 Hz over the temperature range 0.5–35°C is featured for excess static pressures to 60 MPa. The objective of creating an installation is to extend the functional capabilities of the GET 55-2017 State Primary Standard of units of sound pressure and sound particle velocity in a water medium. The feasibility of model operation in GET 55-2017 of the operating conditions of using a hydrophone is shown. The principles of operation and the metrological characteristics of the created installation are examined. The special features of the measurement procedure of calibration of a hydrophone are given.
