pHionics Inc. products

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.

The pHionics STs Series ORP (redox) 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 electrodes provided with the purchase of a STs Series ORP (redox) Sensor and is intended for a wide range of environmental applications. The electrode has an epoxy body with a glass bulb, platinum band, and Teflon™ double junction protection for high stability and longevity in harsh applications.

Custom-made 3/4 inch MNPT compression fitting for pipe mounting of one pHionics STs Series™ water quality sensor.  Unlike compression fittings from other manufacturers, the cmp-k cannot be overtightened so there is no risk of damage to the sensor.  This product is made from chemical-resistant PVDF to withstand harsh chemical conditions.  Not suitable for pressurized in-line applications or temperatures above 30°C. See below for more information on proper installation of sensors using cmp-k.

The patented pHiKlip™ System allows for multiparameter or redundant water quality measurement with up to 4 STs Series sensors.   Each sensor is held firmly in place during operation while remaining easy to snap in or out when needed.
