The advanced

-DIN pH 2000D has all of the benefits of the
advanced pH 2000, but with the additional ability to accept
differential pH or ORP electrodes.
Rugged NEMA 4X (IP66) enclosure can be wall, panel, or post-
mounted for installation in almost any industrial application.
The unit has a large dual-line, backlit LCD that can be adjusted
to display in any lighting condition. The controller can be
operated on 85 to 250 VAC/DC power sources for greater
installation flexibility.
Easily program the controller through the front-panel keypad
and intuitive menus. The controller can be programmed for
on/off (limit), proportional, or proportional-integral (PI) control
with either pulse length or pulse frequency operators. Differential
operation is ideal in situations where electrical noise may cause
problems.
Two control relays can be independently programmed for set
point, delay, and hysteresis to provide extreme control flexibility
in any application. The controller also has a wash relay that can
be programmed for interval and duration to keep the electrode
operating properly. An alarm relay, with programmable delay,
is also included to activate if the set point has been exceeded.
Two-level password protection prevents unauthorized tampering
with settings.
Use controller with differential electrodes to reduce the chance
of reference electrode fouling; order separately at right.
Controller also accepts pH electrodes with 100 or 1000 Pt RTD,
tinned-end temperature sensorssee pages 13001309.

Specifications & Ordering Info
Differential Electrodes
The differential pH and ORP electrodes are
ideal for industrial applications. Differential
measurement technology minimizes ground
loop interferences that can affect standard
electrodes. In addition, a built-in pre-amplifier
allows cable extensions up to 300 feet. Replaceable
heavy-duty quad junction salt bridges and refillable
reference solution extend the life of the sensor in
severe applications, reducing the cost of ownership.
Electrodes have 1

" NPT(M) threads on both ends for in-line
or submersible mounting. A 300 NTC temperature sensor
allows the electrodes to be used as direct replacements for
existing GLI electrodes.
