THe TU7685 Analyser (Controller) together with the TU810/8105 (In-Line) and TU8182 (Dip) Sensors offer the User flexibility in Turbidity Monitoring.

These online monitoring systems are designed for the continuous measurement of Turbidity in water.

The full operating range of the system may be selected by the User from 0-4.000 to 0-4000 NTU or from 0-9.999 to 0-999 mg/l of SiO2, and the sensing system will operate on water streams with temperature from 0 to 50 degrees C.

The measured Turbidity is displayed on a backlit liquid crystal display on the front of the instrument. The Turbidity monitor is well suited for wastewater treatment, effluent monitoring, or stream monitoring.

The mesuring method is Nephelometric.

A light source and a photocell are positioned with their axes 90 degrees from each other. The emitted light is scattered by particles in the process and received by the photocell, in accordance to standard ISO7027.

The Autoclean option delivers high pressure air to the tip of the sensor (TU-8182) to effectively blast accumulated growth from the optical lens. Once installed and placed into operation, the Autoclean Turbidity Sensor will provide months of reliable Turbidity measurement in almost any application. Sensor cleaning frequency is programmable and units are shipped with a default cleaning frequency of once every 24 hours.

Applications include:

• Monitoring of streams and rivers.
• Monitoring of water storage bodies including stratification studies.
• Intermediate and final effluent treatment monitoring.
• Hydrological run off studies.
• Ground and bore water analysis.
• Drinking water filtration efficiency.
• Industrial process monitoring.
• Sludge and dredge monitoring.
