An unbroken record of innovation

Ted Barben introduced the first truly reliable pH sensor in 1964 as the chief scientist and an owner of Uni-Loc corporation. In 1976, Ted and his partners founded TBI to produce their revolutionary wood-cored pH probe, which offered a significant increase in ruggedness and life over traditional double junction probes.

Continuing this record of innovation, Ted and the B.A.T. team developed the patented line of "Axial Ion Path" pH/ORP sensors. The A.I.P. design has proven to deliver up to 6 times the life of competitive probes, with the best performance being in the toughest applications.
