New RATIOMETRIC design in one of the most innovative, WATERPROOF, handheld meters available on the market!
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. Best for colored or extremely turbid samples.
Kits are supplied with 0, 1, and 10 NTU standards (Code 1974-T) or 0, 10, 100 FNU (Code 1974-I), sample bottle, six sample tubes, USB cable and wall adapter—all in a sturdy carrying case.
