DISPOZITIV TERMOMETRIC

摘要

A thermometer or other device for measuring temperatures within a preselected range which utilizes, as a temperature indicating means, a solid, heat expansible substance which melts and expands continuously over the range. Preferred form is an inexpensive single-use disposable clinical thermometer with a plastic casing and a solid indicating means (e.g. a mixture of n-tricosane and n-nonadecane) which expands linearly during fusion over the temperature range of clinical interest.
