[Professional]: This turbidimeter works on the 90° scattered light principle. The instrument is calibrated with the standard solution of turbidity of Formazine as specified by ISO7027. The measurement range of this instrument is 0-200 NTU. The stability of the displayed value is ±1.5% (F.S30min), and the accuracy of the displayed value is 0.1.

[Clear & Readable]: This turbidity meter is equipped with an LCD display with backlight for accurate readings, which can effectively avoid the influence of natural light on the readings. Therefore, it can clearly display the value whether indoor or outdoor. You can take readings at any time.

[TWO Power Supply Options]: This turbidimeter can work on 4 batteries (DC power) or 6V power supply (AC power). The two power supply options make it easy to carry and convenient to measure. You can use it in the lab or take it outdoor. This instrument also has a low voltage indicator to remind you to replace the batteries.
