Broadley-James 5801 Electrode Instructions

Like any other type of pH electrode, Broadley-James models use bodies made of glass to conduct the electrical signal. However, unlike other manufacturers who make constant changes to their electrodes, Broadley-James uses what it calls "backwards compatibility," meaning that any change to their electrodes are compatible with new and old models. Using a Broadley-James electrode begins with calibration.

Things You'll Need

• Distilled water
• Broadley-James pH meter
• 7.0 pH buffer solution

Instructions

• 1

  Unscrew the o-ring holding the electrode to the soaker bottle. Set the soaker bottle aside.

• 2

  Rinse the end of the electrode with distilled water before and after each pH test.

• 3

  Connect the electrode to the pH meter with the supplied coaxial cable. Turn on the pH meter.

• 4

  Dip the end of the electrode in the pH buffer solution. Stir the solution with the electrode for thirty seconds.

• 5

  Read the pH reading from the meter. It should be about 7.0, but if it isn't, you may not have 7.0 pH solution or the electrode is not calibrated properly. Adjust the "standardize" or "zero" control on the pH meter to 7.0 to calibrate the electrode.

• 6

  Rinse the end of the electrode with distilled water.

• 7

  Place the end of the electrode in the testing solution. Wait thirty seconds and then take reading from the pH meter.

• 8

  Rinse the end of the electrode in distilled water and take another reading of the testing solution to ensure the electrode or pH meter isn't malfunctioning.
