HU-200TB-W is a turbidity meter developed to continuously measure turbidity in processes with large turbidity changes, such as water intake and sedimentation tanks in water supply plants. It employs  transmission 90-degree scattered light method and is ideal for monitoring changes in processes with large turbidity changes from low range (10 degrees) to high range (2000 degrees). An electric wiper cleaning  can be installed as an option, and long-term stable measurement is possible by periodic cleaning.

Measurement range

0 – 1000  Degrees(Standard solution:Kaolin)
0 – 2000 Degrees(Standard solution:Formazin)
0 – 100 Degrees(Standard solution:PSL)
