TECHNICAL SUPERIORITY
Hanna panel mount pH, ORP and Conductivity
controllers are designed to meet your most
demanding process control requirements.
Standard features include calibration and self
diagnostic from the front panel touch pad,
4-20 mA output, 2 amp 240 volt dry-contact
control relay (controllers only) and a large LCD
display. When applications require a long
distance between the sensor and controller, a
controller with a 4-20 mA input from a
transmitter is available.
The controllers utilize a sophisticated built in
self-diagnostic function that allows operators
to check whether a malfunction originated
in the controller or from an outside connection.
This unique self-diagnosis system saves
troubleshooting time and costly process
interruptions.
ALARM FEATURES
Hanna controllers incorporate an additional 2
amp 240 volt dry contact relay to provide alarm
warning capabilities. When the solution being
monitored passes the setpoint value of the
control relay, this second relay will trigger and
activate a customer supplied device such as an
alarm, light or a process emergency shut down
Hanna Instruments
contact. The alarm feature is necessary when an
installation is in a remote location and corrective
action must be taken immediately.
RECORDER OUTPUT
The ability to record data from the process you
are monitoring greatly enhances process
troubleshooting. By simply connecting a recorder
to the controller's output terminals (choose
between 0 to 20 mA or 4 to 20 mA according to
your needs), you are able to acquire a hard copy
for demonstrative or analytical purposes.
LOW OR HIGH IMPEDANCE INPUT
Hanna’s pH and ORP controllers come in two
different models to meet all requirements. The
“E” model, has a high impedance 1012 Ohm
direct input from an electrode. Ideal for connections with a distance of up to 33 feet (10
meters). The “T” model, however, is recommended for distances greater than 33 feet (10
meters) and should be used with a 4 to 20 mA
transmitter. The greater the distance between the
controller and the sample, the greater the chance
you have of line noise causing erroneous
readings. Using a transmitter greatly enhances
the input signal, thus allowing high accuracy at
distances of up to 1000 feet (300 meters).
CONSENT FEATURE
The consent contact allows you to be sure that
the ORP dosing occurs only when the pH value
is correct. This assures that the pH is within a
specified range before any dosing of oxidizing or
reducing agents occurs. This will prevent any
overdosing of chemicals, a very important
cost-effective feature in many applications,
especially in pools, spas and hot tubs.
QUALITY CONSTRUCTION
The controller electronics are held in a sturdy
aluminum housing with a shock resistant ABS
plastic front control panel. All controllers come
complete with easy-to-install mounting brackets
and a transparent protective front panel cover.
LED INDICATORS
The LEDs on the front panel light up to indicate
the correct operational mode. The LEDs also
blink at different rates to indicate multiple modes
occurring simultaneously. This feature allows
the user to evaluate the controller from a
distance and clearly read which mode it is in.
