Description

The model 2200D Dissolved Oxygen ana­lyzer/controller is a rugged and depend­able 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 cali­bration and simple operator interface makes
this analyzer/controller a favorite with instru­mentation departments in a wide variety of de­manding 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 naviga­tion. 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 tted 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 submer­sion, ow through and “ball oat” assemblies.

Aquametrix Model 2200D

Dissolved Oxygen Anayzer / Controller

Features

• Dissolved Oxygen

level displayed in PPM
or Percent Saturation

• Intuitive step-through menu

design for quick and easy setup

• Bidirectional control

through two control relays
with independent setpoints
for Relay On and Relay Off

• High/low alarm relay

• ALARM LED on front panel

• Membrane perforation alarm

• Output signal is eld-scalable

meter; in a clean water sample to a lab meter;
in a saturated process; in saturated clean wa­ter and in air. To Calibrate, press the MENU key
until the CALIBRATION LED illuminates. Use
the arrow keys to set the value determined us­ing a calibration method described above. Press
The Enter key twice. The unit is now calibrated.

OUTPUTS

The 2200D provides three analog outputs, includ­ing a 4-20 mA, 0-5 VDC and 0-1 mA. The instru­ment also provides control of external devices us­ing its two independent control relays. An alarm
relay has both high and low set points with a xed
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 bidi­rectional 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 de­termine the fault code. The Operator’s Manual in­dicates the source and likely remedy for the fault.
When the status fault is corrected the STATUS
LED will turn back to green.

for maximum resolution

• Altitude compensation

for maximum accuracy

• STATUS errors illumi-

nate LED on front panel

• Test feature allows simula-

tion of DO readings to test relay
setpoints and analog settings

• Password protection

and watchdog timer

Applications

• Industrial and Municipal

Waste Treatment

• Aeration basin monitoring

• Aquariums

• Fish Hatcheries

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

ENCLOSURE

Model 2200D is packaged in a rugged NEMA 4X
berglass reinforced polyester enclosure. It is ide­ally suited for heavy-duty outdoor applications
such as municipal and industrial wastewater ap­plications.
