Selecting the Conductivity Electrode
Bante900P portable meter is capable of using the three types of conductivity electrodes. Before calibration or measurement, you need to
select the different sensors as per your sample concentration. The table below shows available sensors and its effective measuring ranges.
SENSOR
MEASURING RANGES
CELL CONSTANT
CON-0.1
0.1 to 100µS/cm
K=0.1
CON-1
0.01 to 10mS/cm
K=1
CON-10
0.1 to 200mS/cm
K=10
Conductivity Calibration
Make sure that you selected the cell constant between 0.1, 1 or 10 in the setup menu.
If the current option is “USER”
, the automatic
calibration function will be disabled (Refer to Setup Menu section).
In the automatic calibration mode, the meter allows up to 5 points calibration. To ensure higher accuracy, we recommend that you perform
3 points calibration or select a standard value close to the sample value you are measuring. The meter will automatically detect these
conductivity standard solutions and prompt the user to calibrate the meter. When the calibration is completed, all new calibration values
will automatically override existing data.
The following table shows acceptable conductivity range of calibration solution for each measuring range.

SINGLE POINT CALIBRATION:
1.1 Rinse the conductivity electrode with distilled water, then rinse with a small amount of calibration solution.
1.2 Press CAL key, the meter enters the calibration mode.
1.3 Dip the conductivity electrode into the calibration solution, the meter automatically shows current calibration standard (e.g.
1413µS/cm).
