P3.1 Cell constant Selection
Choosing the right conductivity cell is a decisive factor for obtaining accurate and reproducible
measurements.
One of the most important parameters to consider is to use a sensor with the right cell constant in relation
to the solution under analysis.
The following table relates the sensor cell constant with the measurement range and the preferable
standard for calibration:
Access this setup menu to select the cell constant related to the sensor used:
•
0.1
•
1
- default-
•
10
•
For each of the 3 selectable cell constants, the instrument stores the calibrated points. By selecting the
cell constant, the previously performed calibration points are automatically recalled.
