Good morning

Good morning

Hello can i help You ?

I want to buy calibration for my ORP probe

What system do you have? Or what value do you want?

I would like to have information concerning the calibration and wintering of my PH AND ORP probes

PH7/9

I saw that there are kits

For pH: https://ph-redox-pool.com/solution-calibration-tampon-piscine/1648-kit-d-etalonnage-et-d-hivernage-ph7-ph9.html

For the redox, I need to know the brand and the name of the regulator
