View Product Description

Providing reliable turbidity measurements in Water Treatment Plants since 1959
No.1 Process analyzer supplier to Japanese market*

"Reduce maintenance"

"Digital solution for water quality"

Many of our customers face these challenges - Yokogawa Turbidity Analyzers resolve them.

Since their sales began in 1959, Yokogawa's turbidity analyzers have been continuously developed and improved using various measurement principles suited for multiple applications. With its many achievements, Yokogawa has earned its customers' confidence.

The TB820D is part of the SENCOM4.0 platform family and can connect to FLXA402T. Thanks to a smart unit equipped detector, TB820D gives you more insight into the ordinary operation.

The TB820D turbidity analyzer using the right-angle light scattering method provides highly reliable measurements and uses LED as a light source.
