3.1 Brief description
Measuring
The JUMO AQUIS touch P provides a central platform for the display and pro-
cessing of pH value, redox voltage, electrolytic conductivity, resistance of high-
purity water, temperature, quantities of disinfecting agents such as free chlorine,
total chlorine, chlorine dioxide, ozone, hydrogen peroxide and peracetic acid or
even flow rates. Pulse frequency inputs (counters) are available for flow rate
measurement. Universal inputs can be used to measure analog measurands us-
ing standard signals [0(4) to 20 mA or 0 to 10 V] The unit can measure and man-
age up to 23 parameters simultaneously.
Controlling
Besides numerous simple alarm, limit value or time-controlled switching func-
tions, up to 4 higher-order control loops can be defined in the JUMO AQUIS
touch P at the same time. Tried and tested JUMO control algorithms are used
for P, PI, PD, and PID control in these applications.
Display
A 3.5" TFT color screen with touch function serves to display all parameters as
well as operate and setup the device. The plain text operation philosophy virtu-
ally eliminates the need for a manual. German, English, and, on request, French
are included in the device at the factory as selectable user interface languages
(see order details). Using the PC setup program, the language library of the unit
can be expanded to as many as 15 languages. It's also possible to display lan-
guages that use Chinese and Cyrillic characters. As a result, the device is pre-
destined for global use.
Recording
A paperless recorder is integrated for data recording. Up to 8 analog quantities
and 6 binary signals are registered and displayed on the screen in a time-depen-
dent curve. Storage is tamper-proof and enables official recording obligations to
be fulfilled. The data can be extracted using the JUMO PCC software or to a
USB flash drive for evaluation by the JUMO PCA 3000 PC evaluation software.
