Ion Concentration Calibration
The Bante321 portable ion meter is capable of 2 to 5 points ion calibration with standard solutions, available calibration points include the following options.
MEASUREMENT UNITS
CALIBRATION POINTS
ppm
0.001, 0.01, 0.1, 1, 10, 100, 1000, 10000
mg/L
0.001, 0.01, 0.1, 1, 10, 100, 1000, 10000
mol/L
0.001, 0.01, 0.1, 1, 10
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.
1.1
Press the
Mode
key until the meter shows
icon.
1.2
If necessary, select the concentration unit and ion valence in the setup menu (Refer to page 5
SETUP MENU).
The meter provides three measurement units, including the ppm, mg/L and mol/L, the factory
default is ppm. If the measurement unit has converted, the display will always show
“
CAL
”
and
wait for calibrating the meter.
1.3
Press the
Cal
key, the meter enters the calibration mode. The display shows 0.001ppm (or
mg/L, mol/L, mmol/L).
1.4
Press the
or
key to select the calibration point (e.g., 100ppm). The meter will
automatically perform the calibration from the low to high concentrations.
