Description
Digital sensor for optical turbidity measurment.
The TTurb is a digital sensor used for optical turbidity measurement according to the 90° IR scattered light method. Depending on the sensor version, it can be used in both pure water up to 100 FNU as well as in raw, waste and process waters up to 1000 FNU. The TTurb is available with a 10-meter or a 2-meter cable.
