JUMO AQUIS 500 CR
Transmitter/Controller
for conductivity, TDS, resistivity
and temperature
Brief description
The instrument is used for the conductive measurement/control of electrolytic conductivity,
resistivity or the TDS value. In addition, the JUMO AQUIS 500 CR also offers the possibility of
showing the measured conductivity according to a customer-specific table.
Conductive two-electrode cells as well as four-electrode cells can be connected to the
instrument.
Temperature serves as the second input variable, measured by a Pt100/1000 probe. Depending
on the measured variable, it is therefore possible to implement specific, automatic temperature
compensation.
The instrument is operated using keys and a large LC graphics display on which the
measurements are clearly legible. The plain-text presentation of the parameters makes it easier
for the user to configure the instrument, and also helps in programming it correctly.
Thanks to its modular design, the instrument can be perfectly matched to the particular
application requirement. Up to four outputs are available (see the block diagram for the
functions).
Typical areas of application
Universally applicable in water and wastewater engineering, service/process water and
wastewater, drinking water and well/surface water, pure and high-purity water as well as for
pharmaceutical water (e.g. as per USP, Ph.Eur., WFI), water quality measurements, TDS
measurements (ppm or mg/l).
Key features
• Direct changeover to
- conductivity (µS/cm or mS/cm)
- resistivity (kΩ x cm or MΩ x cm)
- TDS measurement (ppm or mg/l)
- customer-specific table
• Automatic temperature compensation:
off (e.g. USP), linear, ASTM, natural water
(EN 27888/ISO 7888)
• Large LC graphics display with
background lighting
• Choice of display: large numbers, bar
graph or trend display
• Calibration options according to
measured variable: cell constant and
temperature coefficient
• Calibration logbook
• Two-electrode cells (as standard) or
four-electrode cells can be connected
• Pollution detection can be activated
• Auto-range operation
• IP67 enclosure protection
(in surface mountable housing)
IP65 enclosure protection
(for panel mounting)
• Language changeover:
German, English, French;
further languages can be loaded through
the setup program
• Using the setup program: user-friendly
programming, plant documentation,
additional languages can be loaded
