TMS 561

Turbidimeter On-line Process Turbidity Measurement

The TMS 561 Turbidimeter is specifically designed for continuous on-line measurement of turbidity in filtered or raw water in municipal and industrial water treatment plants as well as effluent in wastewater applications. It provides an economical, compact system for turbidity measurement in most water treatment applications. Available with either a white light source, the TMS 561 Turbidimeter is ideally suited for reporting results under EPA and other international standards. Utilizing an EPA-approved, reusable, primary standard, routine calibration is fast and inexpensive.

For poor quality water, an ultrasonic, self-cleaning system is available to reduce maintenance. An optional data acquisition system and software package allows networking of up to 225 turbidimeters into a single computer. The software provides graphical trending, alarms, and filter analysis.
