301DJ-C Plastic ORP Combination Electrode
301DJ-C plastic ORP combination electrode, is suitable for long time
consistent, such as swimming pool water treatment equipment, wasted water
treatment equipment, and solutions containing ion like S- and I-, which may
react with the Ag+ from reference solution and block the junction.
This probe has following features:
- Double junction reference system, able to reduce and avoid junction being contaminated and blocked by tested solution.
- Anti-corrosion POM (Polyoxymethylene) shaft, the protection cap at the top of electrode can be screwed off. It is easy to wash bulb and junction.

Usage and Maintenance
2.1 When measuring, please unscrew the bottle cap, pull out the electrode and
rinse it with deionized water. After using, please put the electrode back into
the bottle and screw the cap tightly.
2.2 The sensitive platinum needle in the front of combination electrode should
not get in touch with hard things. Any damage and hairline crack will make the
electrode invalid.
2.3 The connector of the electrode should be kept clean and dry. If being
contaminated, please clean it with medical cotton and absolute alcohol and
blow dry to prevent the electrode from a shortcircuit and/or slow reaction.
2.4 The electrode’s measuring tip should be soaked in the soaking bottle
containing certain amount of storage solution to keep the junction unblocked.
Clean the bottle and replace the storage solution if the it gets turbid and
mildewed. The electrode should never be submerged in pure water or buffer
solution for long.
2.5 If the sensor or junction is contaminated, pour the electrode into soaking
solution and let it stand for 3 hours after having cleaned it with soft brush
and soapy water.
2.6 After 1-year of use, we recommend replacing the electrode to ensure the
best accuracy.
