The multi-detector optical configuration assures long-term stability and minimizes stray light and color interference. The new ratiometric design allows for easy and accurate testing. The nephelometric mode measures 0-40 NTU/FNU, ratiometric mode 40-1000 NTRU/FNRU and 1000-2000 AU. Now pinpoint the range of interest with better, more reliable results. Ideally suited for low-level drinking water applications, mid-range industrial applications, and high-range environmental applications.
2020t version meets US EPA design criteria as specified by EPA 180.1, Rev. 2.0 (1993) and Standard Methods 2130 B-2001.
2020i version meets design criteria for quantitative methods of turbidity using optical turbidimeters as specified by ISO 7027.
