pH probes
(OP)
We have many pH/ORP applications in our plant. We consistantly have reliability issues on our process streams with a high sodium content. We have used Foxboro Dolphin series, ASTI, and Yokogawa. Anyone tried Metler-Toledo? Any suggestions as to solutions for better reliability?

RE: pH probes
I've gotten extended life from the Honeywell Durafet solid state probe because its reference junction takes a large volume and can be refilled, which we do at least once, sometimes twice.
I got a datasheet for yet another style probe that uses the 'axial ion path" on the reference side for situations that pollute the junction, more than depleting it.
