Tips for unlocking and calibrating a pH probe on a Bio-Pool IV Duo Csa device.

Hello, I would like to calibrate my PH probe on a Bio-Pool IV Duo Csa equipment and I can't remove the probe from its holder. Do you have any advice on how to unblock it without breaking it? Thank you.

I don't see any other solution than pulling vertically!

Is the body of the probe made of glass or plastic?

Plastic, polycarbonate.

OK, so there's less risk of it breaking. Thank you, I will try harder.

Yes, good luck!
