Comment Thanks for the hint. In fact there was no category for this type of measurement instruments. The metrology category tree is still quite incomplete. Therefore I had to create a new category for skin metrology instruments, which is still a too broad category for this image, because there are a lot of instruments measuring on skin (e.g. Skin temperature, skin colour, skin gloss, skin elasticity, etc.) -- Dr. Schorsch (talk) 16:56, 27 October 2018 (UTC)[reply]
Fixed category name
Comment Look at the modified syntax of the scope. On the form it is acceptable on the other hand it is not a measuring instrument that is shown but an explanatory diagram of the principle of measurement. This is what the scope must contain. --Archaeodontosaurus (talk) 06:00, 28 October 2018 (UTC)[reply]
Comment Thanks for your recommendations, it is just too long ago that I was here last time. I have changed the category according to your recommendations. -- Dr. Schorsch (talk) 15:55, 28 October 2018 (UTC)[reply]
