Turbidity and suspended solids sensor
Turbimax CUS50D

Turbimax CUS50D is a turbidity sensor for industrial wastewater and process applications. — Turbimax CUS50D is made for industrial wastewater and process applications. Its sensor head consists completely of a robust, dirt-repellent Teflon derivative.

The sensor housing of Turbimax CUS50D is available in stainless steel and plastic.

Turbidity is the cloudiness of a liquid caused by suspended particles. This video shows how turbidity measuring principles work.

Memosens sensor for turbidity, suspended solids and absorption measurement

Turbimax CUS50D is a smart sensor that allows unattended operation in a wide range of industrial wastewater and process applications. Its absorption principle enables single-point-calibration. Choose from different integrated analytical models to adapt the sensor to your specific application. With Memosens digital technology, Turbimax CUS50D combines maximum process and data integrity with simple operation. It resists corrosion and enables lab calibration.

High level of measurement accuracy and repeatability for stable measurements – in the middle and high turbidity measuring range

High chemical resistance, low maintenance required: Sensor head consists completely of a dirt-repellent Teflon derivative.

The robust plastic version of the sensor is designed for the use in corrosive media or saltwater.

Fast and easy commissioning: Sensor comes pre-calibrated, includes various application models and can easily be adjusted via single-point-calibration.

Automatic sludge model independently selects the optimum signal path for every sludge type.

Perfect process adaption: Fast sensor positioning with a large variety of Endress+Hauser assemblies.
