Lowest Limit of Detection in the Market

Using advanced laser optics and signal processing, the instrument detects increased concentrations of submicron-sized 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. 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.

Meets All USEPA Filter Monitoring Requirements

The FilterTrak sensor uses U.S. Environmental Protection Agency （USEPA） approved Hach FilterTrak Method #10133, the method specified in the USEPA LT2 draft guidance manual for compliance monitoring of membrane filters. The sensor meets all regulatory requirements for individual filter and combined effluent monitoring.

Monitor, Optimize, and Report

USEPA method compliance means that treatment plants with conventional or membrane filtration can monitor and optimize, as well as report, using this single technology.

Compatible with Hach Multi-Sensor, Multi-Parameter Digital Controllers

The FilterTrak sensor can be used with any of Hach€™s sc Digital Controllers. Each sc controller accepts from two to eight sensors. Multiple controllers can be networked to accommodate many more sensors and parameters, reducing the cost per measuring point. Just plug in any Hach €plug and play€? digital sensor and it€™s ready to use without software configuration. €Plug and play€? connectivity means there€™s no complicated wiring or set up. The FilterTrak 660 sc Laser Nephelometer controller system now can manage multiple digital sensors.
