DESCRIPTION AND SPECIFICATIONS
1.1 FEATURES AND APPLICATIONS
1.2 SPECIFICATIONS
1.3 ORDERING INFORMATION AND ACCESSORIES
1.1 FEATURES AND APPLICATIONS
The Solu Comp II analyzers offer the choice of single or dual sensor input with measurement choices
of pH/ORP, resistivity/conductivity/TDS, % concentration, ratio conductivity, total and free chlorine, dissolved oxygen, dissolved ozone, flow and temperature. Dual measurement analyzers offer a wide
choice of measurement combinations thus reducing
the cost per loop and needed panel space.
FIELD COMMISSION OPTION: The Solu Comp II
can be ordered with the ability to commission measurements in the field. This added flexibility can
greatly reduce the number of spare instruments
required for field servicing.
QUICK START PROGRAMMING: Exclusive Quick
Start screens appear the first time the Solu Comp II
is powered up. Screen prompts direct the user to
register the number of sensors, the measurement
unit(s) and the language to display. Some measurement specific prompts are also displayed. The
measurement loop is ready for use in a matter of
minutes.
MENUS: Menu screens for calibrating and registering choices are simple and intuitive. Plain language
prompts guide the user through the procedures.
There are no service codes to enter before gaining
access to menus.
DUAL SENSOR INPUT AND OUTPUT: The Solu
Comp II accepts single or dual sensor input. The
two 4-20 mA outputs can be independently programmed to correspond to any selected measurement or temperature. Output damping and linear or
log output may also be field selected.
ALARMS: The Solu Comp II has three fully programmable alarm relays that can be assigned to
any selected measurement or temperature. Alarms
can be configured as high, low, or USP1. The third
relay has the additional choice of fault alarm operation. When selected, a fault alarm will activate the
relay when a sensor or analyzer fault occurs.
ENCLOSURE: The panel mount version fits standard ½ DIN panel cutouts, and its shallow depth is
ideally suited for easy mounting in Hoffman-type
enclosures. A panel mount gasket is included to
maintain the weather rating of the panel.
Surface/pipe mount enclosure includes self-tapping
screws for surface mounting. A pipe mounting
accessory kit is available for mounting to a 2-inch
pipe.
DISPLAY: The two-line, 16-character, back-lit display can be customized to meet user requirements.
All operations and descriptive messages can be
field selected for English, French, German, Italian,
Spanish, or Portuguese. Informative screens, which
permit data not shown in the regular display, may
be seen at the push of a button.
TEMPERATURE: Most measurements (except
ORP and flow) require temperature compensation.
The Solu Comp II will automatically recognize either
a Pt100 or Pt1000 RTD, normally built into the sensor. When this RTD is present, the Solu Comp II
can be set up to display the temperature in °C or °F
as well as set any one or more of the alarms and/or
outputs to respond to this sensor input. If two measurements with temperature are present either can
be chosen for each alarm and output selected.

MODEL SOLU COMP II SECTION 1.0
DESCRIPTION AND SPECIFICATIONS
For use with any standard pH or ORP sensor and all
Uniloc sensors and junction boxes with built-in diagnostic style preamplifiers, display choices are pH,
ORP or Redox. The automatic buffer recognition feature uses stored buffer values and their temperature
curves for the most common buffer standards available worldwide. The analyzer will recognize the value
of the buffer being measured and perform a self stabilization check on the sensor before completing the
calibration. Manual or automatic temperature compensation is keypad selectable. Change in pH due to
process temperature can be compensated using a
programmable temperature coefficient or isopotential
point. Measurement and display of pH glass and reference impedance helps alert the user to sensor
maintenance needs.

MODEL SOLU COMP II SECTION 1.0
DESCRIPTION AND SPECIFICATIONS
When used with a chlorine specific membrane-covered
amperometric sensor, display choices are free chlorine
or total chlorine. (Total chlorine measurement requires
the use of the Model SCS921 or other sample conditioning system). Because the permeability of the membrane is a function of temperature, a correction is necessary when the sensor is used at a temperature different from the one at which it was calibrated. The
Solu Comp II automatically applies the temperature
correction factor. The process temperature is measured by an RTD in the sensor. An input filter allows the
user to configure the analyzer for rapid response or
low noise. The low noise option is recommended for
samples containing less than 0.1 ppm chlorine.
pH is also a factor in the measurement of free chlorine. An aqueous solution of free chlorine is a mixture
of hypochlorous acid and hypochlorite ion. The relative amount of each depends on the temperature and
pH. Generally, increasing the pH and temperature
reduces the amount of hypochlorous acid in the mixture. Because the response of the sensor to
hypochlorous acid is greater than its response to
hypochlorite, accurate determination of chlorine
requires knowledge of the pH and temperature of the
sample. If the pH is relatively constant, a fixed pH correction factor can be entered into the analyzer. If the
pH is greater than 7 and fluctuates by more than 0.2,
continuous measurement of the pH and automatic pH
correction is necessary. For automatic pH correction,
select code -32 and an appropriate pH sensor.
PERFORMANCE SPECIFICATIONS

For use with most pulse signal flow sensors, the Solu
Comp II's user selectable units of measure include
flow rates in GPM (Gallon per minute), LPM (liters per
minute), or m3/hr (cubic meters per hour), and velocity in ft/sec or m/sec. When configured to measure
flow, the unit also acts as a totalizer in the chosen unit
(gallons, liters, or cubic meters).
Dual flow instruments can be configured as a %
recovery device or a flow difference device.

MODEL SOLU COMP II SECTION 1.0
DESCRIPTION AND SPECIFICATIONS
When used with an oxygen permeable membranecovered amperometric sensor, display choices are
ppb or ppm dissolved oxygen or % saturation.
Because the permeability of the membrane is a function of temperature, a correction is necessary when
the sensor is used at a temperature different from the
one at which it was calibrated. The Solu Comp II
automatically applies the temperature correction factor. The process temperature is measured by an RTD
in the sensor. Calibrating the analyzer is as simple as
exposing the sensor to air and keying in the barometric pressure. If removing the sensor from the process
is impractical, the analyzer can also be calibrated
against a standard instrument. Solubility correction
factors for liquids containing high concentrations of
electrolytes can be registered into the analyzer. The
Solu Comp II automatically calculates ppb/ppm dissolved oxygen taking into account the high salt concentration.
PERFORMANCE SPECIFICATIONS
Measurement Range: 0-20 ppm (mg/L) dissolved
oxygen; 0- 250% saturation
Resolution: 0.01 ppm; 0.1 ppb for 499A TrDO sensor

DISSOLVED OXYGEN (Code -25)
For use with an ozone permeable membrane-covered
amperometric sensor. Because the permeability of the
membrane is a function of temperature, a correction is
necessary when the sensor is used at a temperature
different from the one at which it was calibrated. The
Solu Comp II automatically applies the temperature
correction factor. The process temperature is measured by an RTD in the sensor. The Solu Comp II is
calibrated taking a measurement of the ozone level in
the process by an independent chemical method and
setting the display equal to the measured value. An
input filter allows the user to configure the analyzer
for rapid response of low noise. The low noise option
is recommended for samples containing less than 0.1
ppm dissolved ozone.
