Question about Sanitas Sft 65

This product has the functions or measuring points "forehead" and "ear", which you can select with the buttons of the same name. There are also other models that work without contact and allow a so-called "surface temperature measurement". In my opinion, however, this would be for things and not people, e.g. the temperature of the bathtub water or the surface of the water level. However, this device does not support surface temperature measurement - you can see that from the thin tip, which is primarily designed for the opening of the ear.
