Assistance Guide for Changing and Calibrating Aquaryte Pro and Hayward Pro Probes

Hello, I have an Aquaryte Pro system. I would like to change the probes as they are now 6 years old and I think they are not working properly. When I buy the probes from you, do I need to calibrate them? Or can I just install and use them directly?

Hello, you need to calibrate them as it depends on the probe and the regulator.

What do you mean? What should I do? Because with Hayward probes, you just need to change the probe.

No, you also need to calibrate them if you want an accurate measurement. One moment, let me find the manual.

It's an Aquaryte Pro. I found the manual.

I know, but it's exactly the same procedure and you will need PH7 - P10 and 6502 mV. Sorry, 650 mV.

Perfect, thank you. I will order the probes.

Thank you. Have a nice day.

Hello Olivier, I bought a PH and chlorine probe for a Hayward Pro equipment. Can I just plug it in and use it directly, or do I still need to calibrate it? It seems strange to calibrate a new probe.

Hello, it is recommended to calibrate it as it depends on the probe and the regulator as well.
