pH/ORP Controllers Product Description
The
Global Water 6309POT multiparameter pH/ORP Controller
measures, analyzes, and controls pH, ORP and temperature
in one easy to use unit. The pH/ORP Controller's setup
and calibrations are done through a user-friendly menu
that may be password protected. Calibrations can be
performed quickly and accurately with automatic buffer
recognition of U.S. or European buffer sets, with the
values stored in the pH/ORP Controller's nonvolatile
memory. A large backlit display on the pH/ORP
Controllers provide pH, ORP, and temperature or pH, DO
and temperature measurements, plus the current mA output
and relay status.
The WQ250 multiparameter pH/ORP controllers provide
accurate on/off control via the five programmable relays
or the 4 to 20 mA output may be used for proportional
control. A standard RS-485 output allows for remote
access via PC compatible computer and makes it possible
to link multiple pH/ORP controllers to a common control
system. The pH/ORP controllers built-in temperature and
Automatic Temperature Compensation (ATC) functions may
be used with an ATC type sensor or with a 10K ohm
thermistor.
At power up, the WQ250 pH/ORP controllers perform a
self-diagnostic to ensure proper operation. pH/ORP
controllers electrode efficiency can be displayed to
indicate when electrode maintenance is necessary.
Housed in a watertight (IP65), ¼ DIN case, the 6309POT
pH/ORP controllers include a terminal block that
accommodates the tinned leads and spade lugs on
industrial type pH and ORP electrodes.
NOTES: A BNC to Y adapter is required to maintain the
IP65 rating when using sensors with a BNC connector. A
signal amplifier is required for sensor cable runs over
40 feet.
