Replacement STs Series Dissolved Oxygen Electrode

The pHionics STs Series Dissolved Oxygen Electrode is designed for quick and simple replacement of an old or damaged electrode without requiring any special tools.  This is the exact same as the original electrode provided with the purchase of a STs Series Dissolved Oxygen Sensor and is intended for a wide range of applications, from environmental datalogging to wastewater treatment.

The electrode is galvanic with a large silver anode tip and propionic acid fill solution inside.  The large surface area of the anode ensures a long-lasting electrode with typical lifespan of 6 months to 2 years.
