LaMotte 1974i Turbidity Meter (Model 2020i)
Product Code: 1974i
LAMOTTE WATERPROOF 2020i PORTABLE TURBIDITY METER:
The 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.
- Seven user selected languages - English, Spanish, French, Japanese, Chinese, Italian, and Portuguese
- Advanced calibration algorithms
- Easy menu driven operation and large LCD display
- 500 point data log; stored results can be viewed directly on instrument
2020i meets design criteria for quantitative methods of turbidity using optical turbidimeters as specified by ISO 7027.
Kits are supplied with 0, 10, 100 FNU (Code 1974-I), sample bottle, six sample tubes, USB cable and wall adapter-all in a sturdy carrying case.
