Multiple applications for this conductometer offering conductivity measurements in the range 0.001 microsiemens/cm to 20 siemens/cm with automatic range switching
The Metrohm 712 conductometer has a wide range of uses.
Two lines of 16 alphanumeric characters each are available for the sample identification.
Designation and serial number of the instrument as well as date and time appear on the printout.
A typical GLP component: the last calibration of the measuring cell and the last determination of the temperature coefficient can be verified.
Conductivity measurements in the range 0.001 microsiemens/cm to 20 Siemens/cm with automatic range switching. Temperature measurement from -170C to 500C.
TDS measurements (total dissolved solids (salinity) 0.5mg/l - 300g/l NaCl) With 'frequency auto', the 712 Conductometer automatically selects the measurement frequency best suited to the sample (300Hz or 2.4kHz).
'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.
