Nephelometer Detects Increased Concentrations of Submicronsized Particles


The Hach FilterTrak 660 sc Laser Nephelometer has the ability to detect a 0.3 mNTU or 0.0003 NTU change in turbidity, providing operators with confidence in their turbidity measurement.

Using advanced laser optics and signal processing, the instrument detects increased concentrations of submicronsized particles that are a precursor to larger particles. This allows for early filter deterioration detection that meets or exceeds that of particle counters — all with the day-to-day convenience, simplicity, and reliability of a Hach turbidimeter. Operators can detect impending filter breakthrough, delineate filter ripening, and maximize effective filter run time.
