3000 H is used for the fully automatic
measurement of the total hardness of water.
Instrument models are also available to meas-
ure the carbonate hardness (Plus m-value)
Type SYCON 3000 C and the Minus m-value
Type SYCON 3000 M.
Measurements can be initiated as follows:
1. Press the "START" button on the instrument
control panel.
2. Activate an external remote switch.
3. Automatic - in programmable time inter-
vals.
4. Automatic – after a programmable flow
rate (volume).
After the value of a predetermined limit is ex-
ceeded (overrun) or fallen below (underrun), a
shorter time interval or a lesser flow rate can
be programmed for the following automatic
measurement.
One-component reagents are used for differ-
ent measurement ranges. This enables high
measurement accuracy with minimum use of
reagents, tailored to the specific case of appli-
cation. These reagents can be kept for at least
2 years if stored appropriately (cool, dark).
Water samples with a temperature over 45 °C
must be cooled prior to analysis. In order to
cool down the test water over a cooler only
when the sample is taken, it is possible to trig-
ger a cooling-water valve before the input
valve is opened.
Each measurement begins with an adjustable
flushing phase. This ensures that the water
from the treatment plant is measured and not
the water that has remained in the supply line
since the last measurement.
Subsequently, the measuring chamber is filled
with a new sample. The electrical measure-
ment starts without a switched-on light source
(dark value) and without the addition of the
reagent (blank value). The measurement starts
with the start of the tube pump (regulated by a
stepping motor). During the measurement of
the water hardness, the reagent is continually
added – regulated by a stepping motor - until
a predefined limit is registered. The quantity of
reagent used is a measure of the water hard-
ness.
Signal devices and valves can be switched if a
programmable limit is exceeded or fallen be-
low and a programme mechanism can be ad-
dressed for the regeneration of a treatment
plant.
An analogue output 0(4)-20mA signals the
different states of the instrument. A further
analogue output delivers a signal in propor-
tion to the measured water hardness.
In order to suppress undesired bad-water mes-
sages, the first bad messages can be ignored.
Following the measurement, the measuring
chamber is flushed immediately. This prevents
a premature contamination of the measuring
equipment through the colorants of the re-
agent.
The built-in feed valve is closed during the
analytical pauses to prevent unnecessary water
consumption.
