hello, what is the difference between the probe for ph perfect between the ref PH-1-3-0071 at 59€ and the PH-1-3-0070 at 78€

Hello, there is an impedance diference. Which regulator do you have?

the regulator and a zodiac expert ph and the electrolyser and an expert EI2 I do not see any impedance on the instructions

It's the probe. https://ph-redox-pool.com/gb/zodiac/70-pH-Probe-for-pH-Expert.html
