WTW portable turbidity meter Turb® 430 IR / Set
The WTW portable turbidity meter Turb® 430 IR / Set is a high-precision analytical instrument specially designed for measuring turbidity in various liquids. It is widely used in laboratories, water treatment and industrial processes where accurate turbidity measurements are required. 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 Turb® 355 IR portable turbidity meter, the Turb® 430 IR / Set offers extended functionality and higher precision.
Technical details and functions
The Turb® 430 IR / Set works according to the nephelometric principle (90° scattered light) and uses an IR LED as light source. This enables precise measurements in a range from 0 to 1100 NTU (Nephelometric Turbidity Units) and 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.
