The online Turbidity Monitor (nephelometer, turbidimeter) incorporates a unique Turbidity Probe using LED optical technology to provide an extremely stable, accurate, low maintenance sensor. Combining the sensor with a HydroACT Analyzer/Controller, the system determines true online turbidity and/or suspended solids in water, using a nephelometric measurement of scattered light in accordance with ISO 7027.

Overview
Each probe is equipped with a light source, a side detector for the nephelometric measurement of scattered light from the sample and a reference detector for monitoring the light output. The light source is a long-life IR LED emitter. This configuration allows accurate and reliable measurements of online turbidity and suspended solids to be made. Reliable calibration can be carried out using a single calibration with no need for a ‘zero’ adjustment.
The probes are constructed of stainless steel and sapphire so they can withstand demanding operating environments. An Autoclean system can be included to keep the optical surfaces clean, thereby reducing maintenance to a potential ‘maintenance-free’.
The online turbidity meter is suitable for dip monitoring and mounting in a de-bubbling flow cell.
The operating principle of the online turbidity meter is subject to a patent application and is unique in the way it handles the data it receives in order to calculate a zero, to calibrate and to derive the NTU (FNU) value from the readings.
The Chemtrac online turbidity meters are available with different HydroACT controller options, giving you the same great performance with different communication, display, and control capabilities.
