change the probes on a Zodiac Tri Pro.

Hello,
I have to change the probes on a Zodiac Tri Pro.
How to know its date of manufacture?

Good evening, one moment please

Is this the pH or RedOx probe?

Both ... and your site makes a difference between before / after 2014

Is your current probe like this?

electronic side?
It's a blue BNC plug

or red? I'm not sure which one is which

BNCs each have a blue and red color

No, on the other hand, in both cases there is a BNC.

ok, measuring side, it's a glass probe

Blue is pH, Red is redox.

This is not common, do you know the diameter? would you know how to take a picture?

I can take a picture, but everything is mounted. I still have the boxes of the probes. I'll be back in 3 minutes

Thank you

Very good
