703 Laboratory
Conductivity Meter
The requirements for lab
measurements become stricter
every day. Quality assurance
and measurement documentation in accordance with GLP are
a must in many areas.
With its numerous safety functions
and record printouts at
keystroke, the 703 Laboratory Conductivity Meter considerably simplifies this work for you.
Fullcheck
automatically checks the device
functions during power-on. Also
during operation, a complete
instrument check can be carried
out at a single keystroke. Here, also
display and keypad are checked
besides the electrical characteristics.
Record printouts
With record printouts of the
device self-test, the calibration,
and the parameter settings, it
is possible (as part of quality management to ISO 9000 and GLP) to
document the operability and the
regular maintenance and calibration of the meter.
Sensoface
Sensoface monitors the sensor and
measuring equipment and provides information on sensor selection and handling. It reports clock
memory loss and requests regular
checks in accordance with GLP.
Calibration
Unknown cell constants can easily
be determined with a standard
calibration. The meter automa
tically takes the TC of the calibration solution into consideration,
calculates the cell constant and
displays it. Of course, a known cell
constant can also be entered
82
directly.
Analog output
The galvanic isolation of the re or
c
der output prevents the measured
values from being influenced by
the connected peripherals. Meas
urement continues unimpaired.
EMC
EMC design protects the meter
from electromagnetic interferences, ensuring reliable measurement
results even under unfavorable
conditions.
This makes the Model 703 the first
laboratory conductivity meter that
completely fulfills the EMC recommendations of NAMUR.
The Model 703 offers a wide
range of practical features to meet
the numerous requirements of
everyday measuring tasks.
Automatic switchover to
4-electrode or 2-electrode
operation
With the Model 703 you can use
either 4-electrode or 2-electrode
sensors. The measuring input is
automatically switched to the
appropriate operating mode.
Temperature compensation
manual or automatic
Temperature compensation takes
place either automatically with Pt
1000/NTC 30 kOhm temperature
probes or manually.
Standard RS 232 interface
Via the standard RS 232 interface
your data can be immediately processed by a computer. Even direct
output to a printer is no problem.
GLP records at the press of a key
Records of the parameter setting,
calibration, and device diagnostics
can be output directly to a printer.
This provides you with comprehensive GLP-compatible documentation at the press of a key.
Automatic adjustment of display
range
The meter automatically selects
the display range with the great st
e
possible resolution. Of course, the
desired display range can also be
specified manually.
Easy-to read LED display for two
measured values
The large, bright LED display
allows simultaneous readout of
two measured values, such as conductivity and temperature. The
14-segment display can show
alphanumeric characters.
Double insulation provides elec
trical safety in wet
locations
The well-designed enclosure has
proved successful in practical use.
A waterproof membrane keyboard and drain grooves protect
the meter from moisture. The
robust, stainless steel covered
enclosure resists even strong
mechanical stress.
