Description

 

  • Multi-Parameter Profiler
  • - CTD, Sound Speed, Salinity, Density
  • - Dual Optical Backscatter (OBS) and Nephelometer Turbidity Sensor

  • Bluetooth and USB connectivity
  • Integral GPS receiver for geo-location of profile
  • 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
