LaMotte® Model 2020i Ratiometric Turbidity Meter
Description
LaMotte Ratiometric Turbidity Meter Model 2020i
Thanks to the infrared lamp in this meter, it is ideal for environmental analysis. 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. Other features include: seven user selected languages – English, Spanish, French, Japanese, Chinese, Italian, and Portuguese; advanced calibration algorithms; easy menu driven operation and large, backlit, LCD display; a 500 point data log (stored results can be viewed directly on instrument); waterproof to IP67; a Lithium ion rechargeable battery; and a USB port. Meets design criteria for quantitative methods of turbidity using optical turbidimeters as specified by ISO 7027. Kit is 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.
