An unbroken record of innovation
Ted Barben introduced the first truly reliable pH sensor in 1964. In 1976, Ted and his partners started to produce the revolutionary wood-cored pH probe, which offered a significant increase in ruggedness and life over traditional double junction probes.

Continuing this record of innovation, the patented line of Axial Ion Path pH sensors was developed. 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.

Advantages of BAT pH Sensors include:
• Elimination of focused plugging points between each of five Wood Spool/Junctions,
• Resistance to poisoning by way of longer Ion Paths formed in Axial Ion Path Discs and five natural poison resistant Wood Spools,
• Reduced electrode breakage caused by uneven wood swelling commonly associated with other sensors using glued-in wood references,
• Longer reference life due to a greater volume of concentrated electrolyte surrounding each of the five Wood Spool/Junctions.
