pH Calibration
Bante210 benchtop 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 Buffer Options: pH4.01, 7.00, 10.01
●
NIST Standard Buffer Options: pH4.01, 6.86, 9.18
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 calibration
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 Rinse the pH electrode with distilled water.
1.3 Press CAL key, the meter shows “CAL1/pH7.00”(or “CAL1/pH6.86”).
1.4 Dip the pH electrode into the pH7.00 (or pH6.86) standard buffer solution. Stir the sensor gently.
1.5 Press ENTER key to confirm. Wait for the measured value to stabilize, the display shows “END”. Single point calibration is completed.
2 POINTS CALIBRATION:
2.1 Make sure that you have selected 2 points calibration in the setup menu.
2.2 Repeat steps 1.2 to 1.5 above. When the first calibration point is done, the display will show “CAL2 ”. The meter prompts you to continue with
second point calibration.
