6. Place the correct amount (see Table 6.1 Calibration Volumes)

of pH buffer into a clean, dry or pre-rinsed

transport/calibration cup.

NOTE: Always calibrate with buffer 7 first, regardless if

performing a 1, 2, or 3 point calibration.

WARNING: Calibration reagents may be hazardous to your

health. See Appendix D Health and Safety for more information.

NOTE: For maximum accuracy, the pH buffers you choose

should be within the same pH range as the water you are

preparing to sample.

NOTE: Before proceeding, ensure that the sensor is as dry as

possible. Ideally, rinse the pH sensor with a small amount of

buffer that can be discarded. Be certain that you avoid cross-

contamination of buffers with other solutions.

7. Carefully immerse the sensor end of the probe module into

the solution.

8. Gently rotate and/or move the probe module up and down to

remove any bubbles from the pH sensor.
