MI-800 Micro-ORP Electrode (available in any electrode configuration)

The MI-800 Series Oxidation-Reduction Potential (ORP) Electrodes are available in any micro-combination design listed in our webstie.  A large variety of custom-made configurations are also offered.

 

For example by adding one of the pH glass electrodes 410, 710, 4152, 4154, 4156, 412; to the base MI-800 to specify type for the corresponding Oxidation-Reduction Potential electrodes.

  • CALIBRATION

    Carefully unwind the tape and remove the probe from the protective glass tube.  The white translucent sleeve, which covers the hole, should be moved down the glass barrel slightly to ventilate the reference chamber and replaced after each use. 

     

    The use of a separate Reference Electrode is not required.

     

    The probe can be held by hand when measuring ORP.  Follow the procedure recommended by the manufacturer of your pH meter for calibrating your pH meter with our microelectrode.

     

    OPTIMUM RESPONSE TIME will be obtained after the probe has been exercised

     

    • It is not necessary to rinse the probe because the carry-over is negligible.
  • CLEANING

    Using any electrode in solutions containing protein requires the electrode be rinsed with an enzyme cleaning solution.

     

    After each use, we recommend cleaning our electrodes with Terg-a-zyme (Alconox, Inc.) or a chromic/sulfuric acid glass cleaning solution by submerging the electrodes for a couple of minutes in order to remove all protein from the glass and reference junction.

     

    This will prolong the useful life of the electrodes.

  • STORAGE

    Always clean the microelectrode before storing:

     

    • Long-term (over 2 weeks): Return the probe to its original container and prepare it in the same condition in which you received it.  Usually this means simply moistening the sponge located in the bottom of the protective glass tube with pH 4 buffer.

     

    • Short-term: The probe can be left in an acid pH buffer solution (pH 4.01).
