A sample is extracted in fixed
time intervals (e.g. every 10
minutes) with a fixed sample
volume (e.g. 50 ml).
A sample is extracted in
variable time intervals
(depending on the flow (Q))
with a fixed sample volume.
The sampler is waiting for an
event (e.g. the exceeding of
a pH limit value). A sample is
extracted in fixed time
intervals (e.g. every 10
minutes) with a fixed volume
(e.g. 50 ml) as long as an
event is present.
