Product Description
Time
interval of a
measurement
The measuring interval can be set between 3 and 60 minutes. The
time sequence of a measurement with a measuring interval of
5 min is shown in the diagram below.
The blue bar represents the flowing sample. A short time before the
measurement starts, a zero point measurement is performed. Then
the peristaltic pump starts and a small portion of the reagents [L]
and [M] is pumped into the mixing chamber.
A short time after, when the mixture is in the photometer, the sole-
noid valve [G] is energized and the sample flow through the potom-
eter is stopped. Immediately after that, the total chlorine 1 is
measured. After 120 sec. the total chlorine 2 is measured. After the
measurement is finished, the solenoid valve [G] is de-energized
and sample flows through the photometer until the next measure-
ment starts.
