Client: Hello. Which pH probe for a Zodiac tri pro 18 - please be specific.

Technical Advisor: Hello. Send me a photo of your current probe, no need to dismantle it, I will check. There are 2 possible versions.

Client: It calibrates only with a pH 7.5 calibration solution, no other probe would be suitable. Usually sellers don't specify anything.

Technical Advisor: Both probes calibrate with 7.5. Does your current probe look like this one?

Client: No, that's not it at all - 12 mm in diameter.
