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.

The TB820D is a next-generation digital Turbidity analyzer and connects to FLXA402T. TB820D turbidity analyzer equipped LED as a light source, flat window structure cell, new diagnostic functions, ultrasonic cleaning, etc., and they will reduce your maintenance time dramatically.
Turbidity Detector TB830D utilizes a surface scattered light measurement.
This non-contact method is less susceptible to contamination, reducing maintenance while realizing high efficiency in facility operations with our latest digital sensor technology.
The technology of predictive maintenance prevents accidental shutdown and reduces OPEX.
The FLXA402T is the next-generation analyzer for the Turbidity detector and Chlorine sensor. The FLXA402T can connect up to two sensors of Turbidity, Chlorine, pH, and Conductivity, with digital communications availability.
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.
|Measuring method||Right angle scattered light method||Surface scattering method|
|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)
(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.
