Combination electrodes contain a pH electrode and a reference electrode in one unit. They are available with glass body or epoxy body. Most glass and epoxy body combination electrodes may be used with Tris buffers.

3-in1 combination electrodes contain a temperature sensor in the body of a combination electrode. Temperature compensated readings can be made with a single probe.

Micro electrodes give a quick stable response in a very small amount of sample in a test tube or other small container.

Refillable or gel filled electrodes are available. Many refillable epoxy electrodes have the patented replaceable junction which allows the user to replace a clogged or contaminated junction at a fraction of the cost for a new electrode. Gel filled electrodes require less maintenance and are less expensive than refillable electrodes.
