WTW portable turbidity meter Turb® 430 T
The WTW portable turbidity meter Turb® 430 T is a highly accurate, portable device for measuring turbidity in various liquids. It is ideal for use in laboratories, water treatment and environmental monitoring. Thanks to its compact design and simple operation, it is particularly user-friendly and flexible to use. Compared to similar devices such as the WTW turbidity meter TURB 2120, the Turb® 430 T offers higher accuracy and a faster response time.
Technical details and functions
The WTW Turb® 430 T works according to the nephelometric principle (90° scattered light) and uses a tungsten lamp as a light source. This enables precise measurements in a range from 0 to 1100 NTU (Nephelometric Turbidity Units) or FNU (Formazin Nephelometric Units). The resolution varies depending on the measuring range and ranges from 0.01 NTU for low turbidity to 1 NTU for higher turbidity.
