Product Description

Principle
8
The light beam emitted by the emitter LED [L] passes through the
sample and is received by the transmitted light beam sensor [J].
Some light will be scattered by particles contained in the sample
and received by the scattered light sensor [K], which is placed in a
90° angle to the emitter LED. The ratio between the signal strength
of the signal receiver and the reference receiver is a measure for
the turbidity of the sample.
