Bianconi Sphæra Mundi, seu Cosmographia Demonstrativa Thermoscopium.] 1656 tr. T.

Sci., Lit. & Art 1232/1 The thermometer of Drebbel and Sanctorio..had no scale, and was therefore merely an indicator of changes of temperature, or a thermoscope. b.

Trans. (Royal Soc.) 94 101 An instrument I contrived for measuring, or rather for discovering, those very small changes of temperature in bodies, which are occasioned by the radiations of other neighbouring bodies, which happen to be at a higher, or at a lower temperature. This instrument..I shall take the liberty to call a thermoscope. 1842 W. T. Brande Dict. Sci., Lit. & Art 1232/1 The modification of the air thermometer, called by Leslie a differential thermometer, was claimed by Count Rumford as one of his own inventions, under the name of thermoscope. 1850 W. R. Grove On Correlation Physical Forces (ed. 2) 42 With the most delicate thermoscope, he could detect no indications of transmitted heat. 1860 R. G. Mayne Expos. Lexicon Med. Sci. Thermoscopium, term for an instrument by Rumford for measuring the difference of temperature by dilatation of dry air contained in two balls, which a long tube, twice bent, separates from each other: a thermoscope. c. An electric or magnetic apparatus, as a thermopile, for detecting and measuring minute differences of temperature.

Du Moncel Telephone 195 It is therefore a microphone as well as a thermoscope. 1881 Nature 17 Feb. 372/2 The magnetic thermoscope is intended to indicate differences of temperature by showing differences between the magnetic moments of steel magnets. d. Any substance or device used to indicate excessive heat in machinery, variations of bodily temperature, rate of radiation of heat, or the like.
