Sensorex 3-in-1 combination electrodes are excellent choices for applications requiring pH, Reference, and automatic temperature compensation (ATC). The 3-in-1 operates like 3 separate electrodes, but at a price you would pay for only one electrode of similar function and quality.

Direct Fit Replacement

These electrodes are designed to retrofit the original factory electrodes supplied with your meter, but at substantial savings. Built into the body is an ATC element compatible with your meter.  Combine this with the Sensorex durable and proven S200C epoxy body, and you get a premium quality direct fit, 3-in-1 replacement pH electrode.

Each electrode is supplied with a 30 inch cable and connectors compatiable with your instrument.   All electrodes are supplied with a soaker storage bottle to ensure they are instantly ready to use and to extend their shelf life during non-use.   Select the model to fit your meter from the table below.  If your model is not shown above, please contact  Pathfinder Instruments to determine if a special model is available for your meter.
