712 Conductometer - fast and accurate conductivity measurement
| Conductivity measurement has
top priority when the quality of water samples needs to
be checked. Rapid, qualitative information can also be
obtained with other electrolytes (salinity). |
A wide range of uses
- Conductivity measurements in the range 0.001 µSiemens/cm
to 20 Siemens/cm with automatic range switching
- Two lines of 16 alphanumeric characters each are
available for the sample identification
- A typical GLP component: The last calibration
of the measuring cell and the last determination
of
the temperature coefficient can be verified
- Designation and serial number of the instrument
as well as date and time appear on the printout
- Measurement ranges specially designed for conductivity
titrations with compensation
- Temperature measurement from -170 °C to 500 °C
- TDS measurements (Total Dissolved Solids (salinity)
0.5 mg/L ... 300 g/L NaCl)
- With "Frequency auto", the 712 Conductometer
automatically selects the measurement frequency best
suited to the sample (300 Hz or 2.4 kHz)
- "Auto zero" sets the current conductivity
to zero. Changes can thus be followed with a higher
resolution
- The freely selectable reference temperature allows
matching to the measurement instructions of many
different standards
- The switching, alarm or limit outputs, which can
be used in all measurement modes as a minimum/maximum
make or break contact with hysteresis adjustment,
are popular additional functions for open- and closed-loop
control tasks. You thus save, among other things,
an expensive controller.
- Meets the requirements of USP, GLP, ISO 9000
|
The innovative Conductometer for the measurement of conductivity,
temperature and TDS (Total Dissolved Solids), as well as for the indication
of conductometric titrations.
| Measuring range |
| Conductivity |
0.001 microsiemens/cm to
20 siemens/cm |
| Temperature (Pt100/Pt1000) |
- 170 ... + 500 °C |
| TDS (Total Dissolved Solids) |
0.5 mg/L ... 300 g/L NaCl |
- Automatic determination of the cell constant and the temperature
coefficient of the sample
- Automatic temperature compensation for conductivity measurements
- High Resolution in conductivity and temperature measurements, due
to built in compensation and «Auto Zero» function
- Current output for platinisation of conductivity measuring cells
(Iplat = 20 mA)
- Manual or automatic selection of measuring frequency
- Analogue output with programmable range
- Bi-directional RS 232C interface for PC or printer (results and reports)
- Real-time plot function of conductivity and temperature versus time
on printer
- I/O lines for limit values (min/max) and sample changer
