Although turbidity analyzers was developed for controlling and monitoring drinking water, a turbidity measurement is also required in wastewater plant more and more to achieve sustainable society. Yokogawa started turbidity business since 1959, and our analyzers supplying safety water and saving water pollution around the world. You can find the best solution thanks to excellent technologies proven by experiences.

Use of Right Angle Scattered Light Turbidity Detector TB820D and Surface Scattering Light Turbidity Detector TB830D
The main differences between TB820D and TB830D are shown in the table below.
| Specification | TB820D | TB830D |
|---|---|---|
| Measuring method | Right angle scattered light method | Surface scattering method |
| Measuring Range (Turbidity standard:Formazin) |
0-0.2 to 0-500 NTU (660 nm) 0-0.2 to 0-700 FNU/NTU (860 nm/ Compliant standard: ISO7027) |
0-2 to 0-2000 NTU (White LED) 0-2 to 0-2000 FNU/NTU (860 nm) |
| Sample Conditions (Flow Rate) | 0.05 to 20 L/min | 1.5 to 2 L/min |
| Head tank | Pressurized head tank for low turbidity (for 2 NTU or less) Simple head tank (for over 2 NTU to 10 NTU) Head tank (for over 2 NTU) |
Head tank (optional: Air denoising for Low Range） |
| Cleaning system | Ultrasonic cleaning, automatic wash | Automatic wash |
The TB820D is suitable for measuring tap water and purified water.
The TB830D is suitable for measuring raw water, sewage and wastewater.

Japan's Potable Water Quality Standard was fully revised in 2004, increasing the number of water quality standard items for which tests are required has increased to 50. As items necessary for water quality management, the authority has specified an additional 27 complementary parameters to set the targets for water quality management.
