MIDAS SVX2 Combined CTD/SVP

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

The MIDAS SVX2 is the latest version of Valeport's unique instruments

Recognising the conflict faced by users requiring the superior sound velocity data from an SVP, but still needing the salinity and density data from a CTD, the MIDAS SVX2 combines both technologies to give the best of both worlds.

Now fitted with a 0.01% pressure sensor as standard, the SVX2 also uses synchronised sampling to ensure perfect profiles, and since the digital time of flight SV sensor is the most accurate in the world, it's also possible to compare the true sound velocity data with that generated by commonly used equations.

The unit is fitted with the following sensors:
Sound Velocity
Type: Valeport “time of flight” sound velocity sensor
Range: 1400 to 1600m/s standard. Factory fit option of 1600 to 1850m/s is available
Accuracy: ± 0.03m/s
Resolution: 0.001m/s

Conductivity
Type: Valeport inductive coils
Range: 0 - 80mS/cm
Accuracy: ± 0.01mS/cm
Resolution: 0.002mS/cm

Pressure
Type: Temperature Compensated Piezo-Resistive Sensor
Range: 600Bar absolute (approx 6000m water depth) standard. Others available.
Precision: ± 0.01% Full scale (±0.6m with a 600Bar sensor)
Resolution: 0.001% Full scale (0.06m with a 600 Bar sensor)

Temperature
Type: Fast response PRT
Range: -5 to +35°C
Accuracy: ± 0.01°C
Resolution: 0.002°C
