WTW portable turbidity meter Turb® 430 IR
The WTW portable turbidity meter Turb® 430 IR is a high-precision analytical instrument specially designed for measuring turbidity in various liquids. Thanks to its modern technology and user-friendly operation, it is ideal for use in laboratories, water treatment and industrial applications. Compared to similar instruments such as the WTW Turbidity Meter TURB 2120, the Turb® 430 IR offers higher accuracy and a faster response time.
Technical details and features
The WTW portable turbidity meter Turb® 430 IR 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.
