Aquametrix 2200D Dissolved Oxygen Controller/Analyzer Datasheet User Manual
Aquametrix, Water analytics, Description features applications by
The model 2200D Dissolved Oxygen ana-
lyzer/controller is a rugged and depend-
able industrial grade microprocessor-based
instrument that is extremely easy to use.
Its large, bright LED digital display is clearly
visible even in direct sunlight. It’s speedy cali-
bration and simple operator interface makes
this analyzer/controller a favorite with instru-
mentation departments in a wide variety of de-
manding industrial and municipal application.
Frequently used functions are accessed through
an intuitive step-through menu which is printed
directly on the front panel for ease of naviga-
tion. By pressing the MENU key the operator
scrolls through the menu, illuminating an LED
beside the selected item and displaying the
stored value. Arrow keys are used to change the
value. Seldom used or set-once adjustments,
such as password activation are located on DIP
switches on the back of the swing-out front panel.
INPUTS
The 2200D accepts a sensor input from the P91
sensor. The P91 sensor consists of a probe that
is fitted with a cartridge (P91D) containing a pre-
cisely stretched permeable membrane, electrodes
and electrolyte. The inexpensive and easy to
change cartridge will provide continuous service
for years and is then easily replaced in minutes.
The cartridge is hermetically sealed for long shelf
life. Optional mounting hardware include submer-
sion, flow through and “ball float” assemblies.
CALIBRATION
Calibration can be accomplished by using one
of seven different calibration techniques: in the
process to a portable meter; in clean water to
a portable meter; in a process sample to a lab
meter; in a clean water sample to a lab meter;
in a saturated process; in saturated clean wa-
ter and in air. To Calibrate, press the MENU key
until the CALIBRATION LED illuminates. Use
the arrow keys to set the value determined us-
ing a calibration method described above. Press
The Enter key twice. The unit is now calibrated.
OUTPUTS
The 2200D provides three analog outputs, includ-
ing a 4-20 mA, 0-5 VDC and 0-1 mA. The instru-
ment also provides control of external devices us-
ing its two independent control relays. An alarm
relay has both high and low set points with a fixed
dead band. When this relay is energized, the Alarm
LED on the front panel also illuminates to clearly
indicate an alarm condition. Factory set for bidi-
rectional control, both control relays can be set to
control either a rising or falling process, with easily
programmed Relay On and Relay Off set points.
DIAGNOSTICS
A self-diagnostics program clearly indicates any
system errors or faults by turning the STATUS LED
on the front panel from green to red. The operator
then scrolls through the menu to STATUS to de-
termine the fault code. The Operator’s Manual in-
dicates the source and likely remedy for the fault.
When the status fault is corrected the STATUS
LED will turn back to green.
ENCLOSURE
Model 2200D is packaged in a rugged NEMA 4X
fiberglass reinforced polyester enclosure. It is ide-
ally suited for heavy-duty outdoor applications
such as municipal and industrial wastewater ap-
plications.
