Guide for replacing and calibrating a Corelec Aqualyse pH probe: expert advice.

Hello.
I need to replace my probe for a Corelec Digi PH Aqualyse.
I found the model PH-1-3-0196.
Do I need to buy calibration solution as well?
Should I change the probe holder?

Hello
The calibration solution is ph7 here
If your probe holder is still watertight, there's no need to change it.

Okay. But if I buy the probe on your website, is it pre-calibrated?

No, that's not possible since the calibration depends on your device. However, they are measured.

But in the image, we can see that the probe is immersed in a small container.
So I assume that I have to connect the new probe with the small container at the end of the probe and then start the calibration. Is that correct?

You remove the bottle (it contains a probe conservation liquid), you calibrate the probe with ph7.

Ah! It's not a ph7 liquid! So I need to order a ph7 calibration solution in addition to the probe.

Yes.

One last question: I'm looking for a cap for my probe holder so that I can run the pump without the probe (for calibration). I see two different items and I don't know which one to choose: PS-1638 or PS-1639?

If you have a probe holder, then order this here
The cap is included.

Great!
And a silly question: do I directly immerse the probe in the ph7 solution?
Is the diameter of the bottle large enough?
Can we keep the solution for future calibration?

Yes, it's made for that. But rinse the probe with water beforehand to avoid polluting the solution. And then close the bottle.

Okay, perfect, thank you. I will place an order.
It's great to have a website like yours with such responsiveness through a chat!
Congratulations!

Thank you!
