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 eliminate the need to switch a gain.
