PH / ORP controller
Swan AG

 Measuring and control transmitter in a rugged
aluminum
enclosure
(IP
66).

 Measuring range:
0 to 14 pH respectively -500 to +1500 mV
 Sensor connections for a pH or ORP sensor,
reference
electrode,
Pt1000
temperature
and
for
a digital
sample
flow
meter

(QV-Flow
or deltaT-Flow).

 Galvanically separated sensor connections.
 Automatic temperature compensations ac-
cording to Nernst with or without correction
functions.
 Values for pH buffer solutions and redox
calibration solution programmable.
 Big backlit LC display for the reading of
measuring value, sample temperature,
sample flow, temperature compensation
type and operating status.
 Easy user menus in English, German,
French and Spanish. Simple programming
of all parameters by keypad.
 Electronic record of major process events
and calibration data.
 Real-time clock for time stamp in data logs
and for automated functions.
 Data logger for 1’500 data records stored at a
selectable interval. (Data download to PC requires
optional
HyperTerminal
interface).

 Overvoltage protection for in- and outputs.
 Two current outputs (0/4 - 20 mA) for mea-
sured signals.
 Potential-free alarm contact as summary

alarm indication for programmable alarm
values and for instrument faults.
