Founded in 1982, pHionics designs and manufactures reliable, low-maintenance sensors for pH, ORP, dissolved oxygen, and conductivity measurement. Originally a water treatment system design company, pHionics transitioned to sensor manufacturing by 1991, addressing industry issues such as water ingression and electrode instability.
Their innovative solutions include the pHiConn™ connector system, built-in isolated 4-20 mA transmitters, and the pHiKlip system for multiparameter arrays. Serving industries like technology and research, pHionics’ sensors are known for their ease of use and reliability, backed by several U.S. patents and Small Business Innovation Research awards.
