About pHionics Inc.

pHionics was founded in 1982 and now has over 30 years of experience designing systems for companies such as IBM, Lawrence Livermore Berkeley Labs, Ametek, and Hewlett Packard. During this time, we built our own sensors to withstand the harsh conditions of industrial applications and simplify the operations of our customers.

The design addressed many industry issues such as water ingression, electrode instability/poisoning, complicated installations, and electrical interference. Soon after release, datalogging and water treatment system manufacturers began private labeling our sensors to replace their own. By 1991, pHionics transitioned fully to sensor manufacturing and has been continually improving the sensors since then. Some notable improvements include:

- Early adoption of surface-mount technologies (1987) resulting in industry leading miniaturization
- Extremely reliable double O-ring seals
- Patented pHiConn™ connector system allowing for easy removal of cable or electrode without tools
- Built-in isolated 4-20 mA transmitter in the smallest diameter housing
- Development of the pHiKlip system for implementation of redundant or multiparameter arrays

pHionics’ creative spirit has contributed to the successful completion of several Small Business Innovation Research awards (SBIR Phase l and Phase ll), which—to date—has resulted in the generation of the following U.S. Patents: 6331117, 6612848, 6824394, 6834560, 6993988, and 7293746.

Regardless of what we are researching, our focus remains on providing reliable, low-maintenance, and easy-to-use sensors for pH, ORP, dissolved oxygen, and conductivity measurement—along with excellent customer service to ensure a great experience.
