Ion Concentration Calibration
The Bante932
water hardness meter is capable of 2 to 5 points calibration with standard solutions, available calibration points include the following options.
MEASUREMENT UNITS
CALIBRATION POINTS
mol/L
0.001, 0.01, 0.1
mmol/L
0.001, 0.01, 0.1
In order to get accurate measuring results, we recommend that adding the ionic strength adjuster to all standards and samples. A typical addition would be
2ml ISA to 100ml of standards and samples. If the meter does not calibrated or calibration is not successfully, the display will always show 0.000.
During the calibration, ensure that the selected calibration points cover the anticipated range of the samples.
Calibrating the meter
1.1
Press the
Mode
key until the display shows
, the meter enters the ion concentration
measurement mode.
1.2
Press the
Cal
key, the meter shows 0.001mmol/L.
1.3
If necessary, press the
or
key to select the desired calibration point (e.g., 0.01mmol/L).
1.4
Rinse the water hardness electrode with distilled water, then rinse with a small amount of
standard solution. Place the electrode into corresponding standard solution. Stir the electrode
gently to create a homogeneous solution. Press the
Enter
key, the Calibration icon begins
flashing.
