Turbidity systems

The CUE21 is a compact, online turbidity system that can function at low flow rates. The use of an infrared light source enables measurements that are unaffected by the colour of the water, with an optional white light version which provides measurements according to the standard method described in US EPA 180.1.

The low volume requirement of the flow vessel results in a very fast response time. Reusable and traceable turbidity standards along with simple operation make calibration easy. A full-time ultrasonic cleaner reduces maintenance and prevents air bubbles sticking to the glass.

A desktop laboratory turbidity meter is also available for research and routine measurement and has an identical sample vessel to the online measurement system, thus using the same turbidity standards as the online turbidity meter. The desktop turbidity meter’s integrated RS232 port enables data storage and printing. An automated calibration alarm ensures calibration is not neglected.

The portable version of the turbidity meter, like the online and laboratory devices, is based on light-scattering measurement in accordance with EN ISO 7027 and US EPA 180.1. It comes with a robust, waterproof storage box containing batteries, basic operating instructions, measuring vessels and reusable calibration standards.
