ABSTRACT:
A clinical thermometer with maximum function with a non-toxic eutectic Ga alloy as measuring fluid 14 inside a measuring tube 13 which provides adhesion forces larger than the cohesion forces inherent in liquid 14. To reach the maximum function, therefore, the customary Hick'sche constriction is not required any more facilitating production and handling of said clinical thermometer. Furthermore, a special Ga/In/Sn alloy is described, which may be used not only for clinical thermometers but also as a lubricant.
