1.1.2 Purpose of the Product
The TB Series Portable Turbidimeter isdesigned to analyze aqueous samples that are
collected into a glass vial that is then capped. The vial is prepared for measurement
using a scrupulous technique to minimize interferences from dust and scratches. Once
prepared, the vial is placed in the instrument for measurement.
The instrument can be used in the laboratory or taken to the field to perform
measurements on samples as they are collected.
