Inline turbidity sensor
OUSTF10

Turbidity and suspended solids measurement by light scattering and absorbance

The OUSTF10 scattered light turbidity sensor is used for measurement of suspended solids, emulsions and immiscible fluids in process liquids. It provides you with all desired information from product purity to filter blocking. As a result, you gain more control over the quality of your products and processes. OUSTF10 is ready for all kinds of environments, such as very high temperatures, hazardous areas (ATEX, FM) and hygienic processes (CIP/SIP).
