WebThermistors are made up of metallic oxides, binders, and stabilizers pressed into wafers and then cut to chip size, left in disc form, or made into another shape. The precise ratio of the composite materials governs their … An electronic thermometer works by putting a voltage across its metal probe and measuring how much current flows through it. If you put the probe in boiling water, the water's heat makes electricity flow through the probe less easily so the resistance goes up by a precisely measurable amount. See more Not all thermometers work this way, however. The one shown in ourtop photo has a metal pointer that moves up and down a circularscale. Open up one of these thermometers and you'll see the pointeris mounted on … See more One problem with mercury and dial thermometers is that they take awhile to react to temperature changes. Electronicthermometers don't have that problem: you simply touch the thermometer probe … See more If you want to measure something that's too hot or cold for a conventional thermometer tohandle, you'll need a thermocouple: a cunning devicethat measures temperature by measuring electricity.
