Valeport’s SWiFTplus Multi-Parameter Profiler with a Turbidity sensor combines survey-grade sound speed, temperature and pressure sensor technology with Turbidity observations.
The package is completed with the convenience of Bluetooth connectivity, rechargeable battery and an integral GPS module to geo-locate each proﬁle.

Dual Optical Backscatter (OBS) and Nephelometer Turbidity Sensor
Bluetooth and USB connectivity
Integral GPS receiver for geo-location of proﬁle and time synchronisation
Rechargeable Lithium-ion Battery
Dedicated PC software and iOS portable device App
Valeport’s Turbidity technology is essentially two sensors in one. The ﬁrst is a “classic” nephelometer, using a 90˚ beam angle for turbidity levels between 0 and 2,000 NTU. The second sensor uses Optical Backscatter (OBS) for turbidity levels up to 10,000 NTU. The sensors output data separately and simultaneously at a programmable rate. This means that there is no need to switch ranges as conditions vary. Intelligent sampling and the use of a 24 bit ADC eliminates the need to switch gain.
Nephelometer: 0 to >1 ,000 NTU - linear response1 OBS: 0 to >4,000 NTU - linear response 1 & 2 1 depending on suspended material 2 >4,000 NTU has a non-linear monotonic response that allows derivation of higher values using look-up tables\secondary calibration

Some users need the superior Sound Velocity data from an SVP with the Salinity and Density data from a CTD. So Valeport has come up with the unique MIDAS SVX2 that combines both technologies to give the best of both worlds.
