Suspended solids sensor
Turbimax CUS51D

Turbimax CUS51D is a smart suspended solids sensor for unattended operation in water and wastewater.

Turbimax CUS51D measures suspended solids and turbidity.

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

Memosens sensor for suspended solids and turbidity measurement in water, wastewater and utilities

Turbimax CUS51D is a smart sensor that allows unattended operation in a wide range of process conditions. Its unique design is extremely robust and it is also low-maintenance thanks to its self-cleaning functionality. Choose from different integrated analytical models to adapt the sensor to your specific application. With Memosens digital technology, the CUS51D combines maximum process and data integrity with simple operation. It resists corrosion and moisture and enables lab calibration.
