pHionics

The pHionics STs Series™ pH sensor/transmitter provides highly accurate pH measurement from 0-14 pH. The electrode is glass with a silver/silver chloride reference wire and double junctions to ensure long-term stability in harsh chemical solutions.

The STs Series Dissolved Oxygen combines a dissolved oxygen and temperature sensor along with a 4-20 mA transmitter into one durable, compact device.

The STs ORP (redox) provides ORP (redox) and temperature outputs with a 2-wire, 4-20 mA transmitter in a single, compact device.

pHionics has combined a conductivity and temperature sensor with a 4-20 mA transmitter into a single, compact device that provides exceptional durability and accuracy.
