Multi-parameter Instruments
WTW multi-parameter instruments solve the problem of multiple electrode interference by utilizing our advanced sensor
technology. With simultaneous functions for pH, ORP, dissolved oxygen, conductivity, salinity and temperature, these
­compact meters are complete, all in one laboratories, making it possible to measure oxygen, conductivity and pH
­simultaneously in the same sample vessel or field location.
Long battery life or optional line adaptors allows WTW’s multi­
parameter instruments to be used either in the laboratory
or in the field. The data logging function insures ­accurate
62
reporting. Our standard automatic documentation storage,
user defined calibration procedures and GLP functions ­provide
comprehensive quality assurance.

Laboratory Multi-parameter Instruments
With the growing number of measurements required by today’s laboratory, instruments need to be able to ­perform
­multiple functions. The inoLab® multi-parameter instruments provide the essential features and functions for safe and
­reliable measurements.
inoLab® 720/7200*
• Compact
• Versatile
• Easy-to-use
inoLab® pH/Cond 720/7200* and inoLab® Multi 720/7200*
The inoLab® pH/Cond 720/7200* is a meter for initial
processing of routine pH/conductivity measurements. The
inoLab® Multi 720/7200* allows the measure­ment of pH
and ORP, dissolved oxygen, conductivity and salinity as
well as temperature. The instruments are suitable for
­standard measurements where GLP-documentation is not
required.
Additional features:
• Easy-to-clean, touch-sensitive keypad
• Simplified operator convenience
• Bench and wall-mounted models
• Can also be operated on battery power
• Country-specific units
• Application-oriented displays
inoLab® 740/7400*
• Multi-functional
• Precise
• Communicative
inoLab® pH/Cond 740/7400* and inoLab® Multi 740/7400*
As high-end instruments, the inoLab® pH/Cond 740/7400*
and the inoLab® Multi 740/7400* have a resolution of
0.001 pH units. They also have all the functions necessary
for making ion selective measurements. With the inoLab®
Multi 740/7400* dissolved oxygen is measured as %, mg/l or
mbar. The pH/Cond 740/7400* and the inoLab® Multi 740/
7400* can be used to measure the salinity and TDS (Total
Dissolved Solids) as well as con­ductivity and specific resistance.
The optional built-in printer as well as the graphic display
with operator guidance increase the measuring convenience
and allow QA-compliant documentation.

Additional features:
• 5-point calibration by linear regression
• Freely selectable buffer sets
• Graphic evaluation possible
• Built-in digital plotter
• Connection for bar-code reader or PC keyboard
• User selectable languages

In addition to pH and ISE capability, and with features such
as the ability to measure salinity, TDS, specific conductance, resistance and temperature coefficients, this versatile meter can perform all required conductivity measurements. Temperature coefficients are pre-programmed for NaOH, HCl, KCl, and NaCl. Plus,
individual (non-) linear coefficients can be
entered into the instrument. Additional
features include the measurement of
sample concentrations by conductivity and two dimensional temperature ­concentration field to
determine accurate reference
conductivities. Comprehensive
additional functions such as
­measurement data management,
PC-connection via MultiLab® pilot,
­GLP-compliant calibration and measurement data
­acquisition and a bidirectional RS 232 interface permit
seamless integration into contemporary laboratory routines.

Portable Multi-parameter Instruments
ProfiLine Portable Multi-parameter Field Meter
The WTW ProfiLine Multi 1970i, supplied with integrated powerful NiMH rechargeable batteries, is both waterproof
(IP 66) and submer­sible (IP 67). With its RS 232 output, real-time clock and 500 data file data logger, this rugged meter
conforms to all GLP requirements. It allows the simultaneous connection of pH, conductivity and dissolved oxygen probes.
The parameter to be measured is set in the display via the “M” function key and can then be measured or stored. Comes
e­quip­­ped with a han­dle and carrying strap.
ProfiLine Multi 1970i
The Multi 1970i has a built-in preamplifier and is therefore
suitable in combination with the WTW depth armatures for
­single-parameter operation at depths down to 100 m (330 ft).
• Robust, shockproof
Up to three depth armatures can be simultaneously connected using the adapter ADA/TA 197 pH.

ConOx
• Slender
• Convenient
• Measures conductivity, dissolved oxygen and temperature simultaneously
MPP 350
• pH, conductivity, dissolved ­oxygen
and temperature ­at the same time
• For all areas of application in surface
waters and 2 inch boreholes
• Depth measurement up to 100 m (330 ft)
Conductivity and dissolved oxygen measurement with
fully automatic salinity correction.
The ConOx sensor is a combination probe that allows for
the simultaneous measurement of conductivity, dissolved
oxygen, and temperature, and features automatic salinity
correction as well. The conductivity portion of the sensor
incorporates a proven 4-electrode system which helps to
prevent inaccurate readings sometimes caused by difficult
or dirty samples. The DO portion of the probe is a ­galvanic
sensor that allows for immediate use after cleaning – eliminating the required “warm-up” time associated with other
probes. The ConOx requires little maintenance and is suitable for all water analysis applications, whether in the laboratory or field environments.
An all-new Multi-parameter probe, perfect probe for
use with the Multi 350i/3500i*:
The MPP 350 is designed for use with the Multi 350i/3500i*
with a diameter of 41.5 mm (1.6 in.) and a length of
290 mm (11.42 in.), providing versatility for a wide range
of applications. The MPP 350 allows for the simultaneous
measurement of pH, dissolved oxygen and conductivity
suitable for use in lakes, rivers, saltwater, brackish water,
ground water or spring water, or for measurements in boreholes down to a maximum depth of 100 m (330 ft.). The
special pH sensor SensoLyt® MPP-A (sold separately) provides reproducible measurement values even at low conductivity levels. The conductivity cell, with proven 4-electrode measurement technology, has a range of 1 µS/cm to
2 S/cm. The MPP 350 is available with 8 different cable
lengths up to 100 m (330 ft).
