1.3.7 Composite and Discrete Overview
Discrete Sampling (PVS4100 and PVS4120 only) is sampling wherein
samples are taken into more than one container. Inside of the cooling chamber
is a stepper assembly which revolves 360° and delivers samples into separate
containers, ranging from 8 to 24 bottles. Discrete sampling is beneficial in
situations where change over time needs to be measured, such as measuring
different water characteristics over 24 hours. Labs and monitoring personnel
tend to rely on discrete portable sampling.
