    This section provides a detailed presentation of the OCEAN SEVEN sensors. LIFETIME AND HOW TO REPLACE THE IDRONAUT SENSORS The IDRONAUT sensors are all pressure compensated and, in particular, the physical sensors (pressure, temperature and conductivity) can last many years, if properly used. They are high-quality sensors, as they are well known by oceanographers to measure salinity with great accuracy.
