Aqua Scat 2 HT
Aqua Scat 2 HT
On-line turbidity meter for water treatment
Description
AquaScat 2 HT is a turbidity measurement system designed for precise monitoring of untreated water, sedimentation processes, and turbidity levels before and after filtration. It uses a non-contact free-fall measurement principle that prevents optical contamination and ensures long-term measurement stability. The system delivers extremely low background turbidity with very low maintenance requirements, making it highly reliable in continuous operation. Verification is simple using a solids reference, while operation is intuitive thanks to the integrated color touchscreen display. Aquascat 2 HT is ideally suited for drinking water treatment, wastewater treatment, and process water applications across a wide range of industries.
