2.5.9 Verification
1. Sensor still being in pH-10 buffer solution, control
should display a pH of 10 (+/-0.10).
2. Take sensor out of the pH-10 buffer solution and
rinse well, then, dip it in pH-4 buffer solution.
3. Wait for sensor to stabilize. Control should display
a pH of 4 (+/-0.10).
4. Take sensor out of the solution and rinse well.
5. Take thermocouple out of the solution; rinse well
before storing.
2.5.10 Disposal of Buffer Solutions Used for
Calibration
1. Empty buffer solution from the two beakers, one
after the other into a large quantity of cold water.
2. Check pH of this solution using control sensor just
calibrated. If pH reading is <
6 or > 9.5, add
NaHCO
3
, a little at a time while stirring, until pH
drops between 6 and 9.5, discard solution in the
sink.
3. Rinse beakers well.
4. Rinse sensor well. Dab sensor tip with a soft lint-
free cloth to remove excess of water.
5. Reinstall pH sensor on washer.
6. Refer to I
