ABSTRACT:
A method for the manufacture of a thermometer provides for a bulb being formed on the thermometer capillary, a bulb receptacle being formed on the lower envelope tube end and at least over part of the receptacle its inner contour exactly corresponds to the outer contour of the bulb. The thermometer capillary is then introduced into the envelope tube and the bulb is accurately fitted into the lower part of the receptacle. In the case of a thermoareometer, the receptacle particularly serves as a weight for receiving the necessary weight-providing material, such as copper or the like.
