PH Pufferlösung Kalibrierlösung Eichlösung (pH 9.182)

All pH electrodes require calibration from time to time. A two point calibration characterizes an electrode with a specific pH meter. Once an electrode is characterized, the electrode/meter pair can be used to determine the pH of a solution. Please follow the step-by-step procedure outlined below to perform a two point calibration. A 6.864 pH buffer solution and a 4.003 pH buffer solution are required.

1) Rinse the electrode thoroughly with D.I. water to remove all traces of storage solution, process medium, or previous test solution. Thoroughly rinse the electrode after each buffer test to prevent carry over contamination of the pH buffer solutions. Gently blot the electrode on a soft tissue to remove the excess rinse water. Do not rub the bulb since it can cause a static charge build-up.

2) Insert the electrode and the A.T.C. (automatic temperature compensator) in 9.182 pH buffer solution. Allow 30 seconds for the electrode/A.T.C. to reach thermal equilibrium with the buffer solution. Adjust the pH meter with the standardize/zero control for a pH indication equal to 6.864.

Note: If the meter does not have an A.T.C., place a thermometer along with the electrode in the 9.182 pH buffer solution. Allow 30 seconds for the pair to reach thermal equilibrium with the buffer. Adjust the temperature dial on the meter to correspond with the thermometer reading. Then adjust the pH meter with the standardize/zero control for a pH indication equal to 9.182

Notes:
a) Always use fresh pH buffer solutions for the most accurate results.

b) When a pH electrode is calibrated with an autocalibration meter, consult the meter’s operation manual for the required calibration procedure.
