The CDCN13 is a fully programmable controller designed for
complete chemical automation (conductivity, pH and ORP) as well
as control of chemical additives, all with data logging, RS232
communications, and available RS485. This controller can easily
handle cooling tower, boiler, industrial process water, food
processing, drinking water and wastewater treatment applications.
Featuring high accuracy and easy installation and operation,
engineering units can be displayed in either US or metric values
using the 16-button keypad and the large, 8-line LCD readout with
simple scroll-through menus. Standard features include
conductivity control, with the ability to control 4 additive feed
programs. You can get a readout of the probe temperature. pH and
ORP measurement and control is available, as is a safety flow
switch contact, and RS485 communications.

The CDCN13 has 8 control relay outputs, for up to 4 chemical
additives, fill valve, bleed valve, probe rinse, and remote alarm.
Standard features also include dynamic probe failure testing for
pH/ORP sensors, allowing the controller to detect a probe failure
quickly after it occurs, so the user can avoid dangerous out-of­range conditions. The automatic probe rinse can be used for either
manual or automatic cleaning of pH or ORP electrodes.

Comes complete with operator’s manual and 3V lithium battery. Probes sold separately.
Note: When ordering the conductivty or pH controller, it is recommended to purchase pH buffer solution, such as PHA-7, pH buffer 7 and

conductivity standard solution, such as CDSA-1413, 1413 µS/cm.
Ordering Examples: CDCN13, conductivity controller, CDE10, conductivity sensor, CDSA-1413, conductivity standard solution, 1413 µS/cm,

$2550 + 205 + 23 = $2778.

CDCN13-PH-A, conductivity/pH controller with 4 to 20 output, PHE10, pH electrode, PHA-7, pH 7 buffer solution, $3750 +195 + 5 = $3950.
