WiSens CTDSV: Conductivity, Temperature, Depth, Salinity and Sound Velocity

The WiSens CTDSV data logger measures and records conductivity, pressure and temperature over a depth range from 0 to 300 meters. Salinity is deducted by calculation. The WiSens CTDSV is fitted with a Sound Velocity sensor.

 Fast wireless configuration and data collection thanks to the Wi-Fi communication

 Compatible IOS, MAC OS, Windows, Android

 Easy maintenance

 Optimal protection of the sensor

 Lithium batteries for long-term use (up to several years)

 Aerotransportable lithium batteries

 Copper-based anti-fouling replaceable sensor protection
