Bante210 Benchtop pH Meter
pH Calibration
The Bante210 pH meter allows 1 to 3 points calibration. We recommend that you perform at least 2 points calibration for high accuracy measurement. The
meter will automatically recognize and calibrate to following standard buffer values.
USA Standard Buffers
NIST Standard Buffers
Single point calibration should only be carried out with pH7.00 or 6.86, otherwise calibration will not be accepted.
The meter must be calibrated prior to first use or new electrode replaced. To ensure accuracy, regular calibration is recommended. DO NOT reuse the pH
buffer solution after calibration, contaminants in solution will affect the calibration and eventually the accuracy of the measurement.
Single point calibration
1.1 Make sure that you have selected 1 point calibration in the setup menu.
1.2 Press the key, the meter shows CAL1/pH7.00 (or CAL1/pH6.86).

1.3 Rinse the pH electrode with distilled water, place the electrode (and temperature probe) into the pH7.00 (or 6.86) buffer solution. The end of the
electrode must be completely immersed into the calibration solution. Stir the electrode gently to create a homogeneous solution. Press the
key, the meter begins the calibration, the Calibration icon continuously flashing.
1.4 Wait for the reading to stabilize, the meter automatically shows END. Single point calibration is completed.
