Description

AquaScat S is a compact sensor for the measurement of turbidity and temperature directly in water, designed to ensure reliable and continuous monitoring in water treatment processes. Thanks to its high measurement accuracy, it ensures accurate results even in the presence of reflective piping, contributing to the effective monitoring of treated and process water quality.

The instrument is particularly suitable for monitoring UV systems, ultrafiltration systems, tanks and water distribution networks, as well as for measuring turbidity in treated water and process water. Comparison with a secondary turbidity standard helps maintain high control reliability over time, while minimal maintenance reduces operating costs and simplifies plant management.

AquaScat S is available with different installation variants and process connections, allowing easy adaptation to different plant configurations. In addition, it offers multiple options for the display and transmission of measured data to the process control system or SCADA, ensuring perfect integration into modern automation systems.
