Good morning, with this PH probe ARTICLE NO.: PH-1-3-0118 I would like to be sure that the diameter of the glass body is 12 mm and can still be calibrated with 7.5 calibration fluid as my Zodiak Tri Pro from 2011 is and offers both recordings 12 mm (squeeze coupling) or 21 mm thread for W500710 via adapter

Hello

Thank you in advance and have a nice day

Yes, this probe is 12mm in diameter. It can be calibrated at 7.5mm

Please confirm that your current probe does not look like this.

If your current probe does not match the above, you have selected the correct probe

... the beginning of 2011 was with the 12mm probes and from about 2016 with the thick ones (according to your picture) which were much more durable, which item no. I would have to buy then.
