Knick 703 Laboratory Conductivity Meter

Model 703 Conductivity Meter offers numerous safety functions and record printouts at keystroke, as well as a wide range of practical features to meet the numerous requirements of everyday measuring tasks.

Fullcheck
Automatically checks the device functions during power-on.

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 automatically 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 directly.

Analog output
The galvanic isolation of the recorder output prevents the measured values from being influenced by the connected peripherals.

EMC
EMC design protects the meter from electromagnetic interferences.

Automatic switchover to 4-electrode or 2-electrode operation
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 greatest possible resolution.

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.

Double insulation provides electrical safety in wet locations
The well-designed enclosure has proved successful in practical use.
