Care and Use

ORP electrodes usually start performing poorly because of problems with the probe. The two parts of the ORP probe that cause problems are the glass sensing bulb and the reference junction.

Sensing bulb

The glass bulb loses sensitivity with use and will eventually fail. This is true of all ORP probes.

Reference junction

The reference junction is a small hole that allows the meter to compare the sample to a reference. The reading is generated based on the electrical difference between the sample and reference. If the junction hole gets clogged, the ORP electrode will no longer function.

You can extend the life of your ORP electrode in the following ways.
