can you tell me the difference between the dual link zodiac ph probe at 79€ and the tri pro ph probe after 2014 at 89€

Hello

Your probe looks like this:

or ?

to date I have a probe like the blue and black

then in this case you need this one: https://ph-redox-pool.com/zodiac/456-sonde-ph-pour-sonde-ph-pour-zodiac-tri-pro-ph-aprés- 2014.html

for assembly you need a kit where the thread is compatible

No, just screw it in place of the current probe

OK, thanks
