hello I have a zodiac expert ph regulator, on your site there are 3 probes for this model expert, expertv2, expertv3. what does v2, v3 correspond to?

Hello, it depends on the probe you currently have. send me a photo of your current probe. no need to disassemble it

A moment

This one

thank you, I just looked at the details of the expert probes, v2, v3, it's exactly the same thing what justifies the price difference of these 3 probes?

Electrically it is the same. The difference is the mechanics for mounting

On your photo, I see a filtering hence the choice of v3

on the v2 there is also a thread

Yes, but in the down position and it is another thread

according to the photos, mine corresponds to the V2, the threading is not linked, the top is blue and I can lift it as in the photo of the V2 while on the V3, the threading seems to be in one piece with the top thank you

You have v3

The v2 replaces the probe on the right in the photo

sorry but I don't understand, here is a new photo of my probe which corresponds exactly to probe v2

No, the original v2 is like this

my regulator is 3 years old and the probe is original and corresponds to the photo on the site but not the one here

I know, you need v3. If there was a problem, we guarantee it:https://ph-redox-pool.com/gb/content/15-compatible-or-refunded

The probe: https://ph-redox-pool.com/gb/zodiac/3113-ph-probes-for-ph-expert-v3.html

sorry but I do not understand why I have to take V3 when on your site, v2 corresponds completely to mine and in addition it is less expensive

Sorry, but the probe you photographed does not match the last photo.

The body is transparent.and in the photo it is black

this is yours

and this is mine the top is blue, no black screws and transparent tube

Sorry, I confused it with tri Expert. You need v3. the v2 you see will not mount

I think I just understood, the thread of mine is on the blue part while on the V2 of your site, it is on the black part
