TB820D and TB830D Sampling System Selection Manual
Introduction
This manual describes how to select a sampling system when the analyzer combined with the
“TB820D Right Angle Scattered Light Turbidity Detector” and “TB830D Surface Scattering Light
Turbidity Detector” does not have an assemble stanchion.
If you specify without a sampling device (Su󰀩x code -NN, -A5), you have to select and build
system components such as a head tank, solenoid valve, and manual valve. This document
describes how to select the solenoid valves and head tanks necessary for conguring a sampling
system, as well as piping and wiring diagrams.
