DOCN601 Series Dissolved Oxygen
analyzers/controllers are a rugged
and dependable industrial grade
microprocessor-based instruments
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 applications. 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.
The DOCN600 Series accepts a
sensor input from the DOE-601 sensor.
The DOE-601 sensor consists of a probe
that is fitted with a DOE-601-SC cartridge
containing a precisely stretched permeable
membrane, electrodes and electrolyte. The
inexpensive and easy to change cartridge takes
only minutes to replace. The cartridge is
hermetically sealed. Optional mounting
hardware includes submersion and “ball
float” assemblies.
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 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.
The DOCN600 Series provide three analog
outputs, including a 4 to 20 mA, 0 to 5 Vdc
and 0 to 1 mA. The instrument also
provides control of external devices using
its two independent control relays. An
alarm relay has both high and low setpoints
with a fixed deadband. 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 setpoints.
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.
DOCN600 Series is packaged in a rugged
NEMA 4X fiberglass reinforced polyester
enclosure. It is ideally suited for heavy-duty
outdoor applications such as municipal and
industrial wastewater.

Note: Comes complete with operator’s manual.
DOE-601 is the sensor only; the sensor cartridge DOE-601-SC is required for operation.
Ordering Example: (1) DOE-601 1 1/4, ¥6,625.00, plus (1) DOE-601-SC Sensor Cartridge, ¥4,125.00, ¥6,625.00 + 4,125.00 = $10,750.00
