Product Introduction

ACATS430 is a compact, yet extremely robust turbidity sensor capable of measuring turbidity and total suspended solids (TSS) concentrations up to 4000 NTU or 20,000 mg/l.

With a choice of hermetically-sealed stainless steel or titanium versions, each featuring scratch-resistant sapphire optical windows, the ACATS430 provides a versatile solution for use in benign environments through to those featuring aggressive or corrosive media.

Supplied fully factory-calibrated ready for use straight out of the box.

Users benefit from:

no servicing for the lifetime of the sensor;

in-situ cleaning;

advanced predictive maintenance diagnostics;

adaptive TSS calibration feature for improved process control;

simplified calibration;

flexible installation;

certified performance;

Product advantages
