A liquid in glass thermometer is the sensor one visualizes most often for temperature measurement. A glass cylinder with a bulb at one end, a capillary hole down the axis, connected to the reservoir in the bulb filled with silvery mercury or perhaps a red-colored fluid, an engraved temperature scale; that’s what I picture in my mind’s eye as a proper thermometer.
There are many designs and a significant range of capabilities and uses of those designs. There are many variants around the world from simple, low cost devices that are used to indicate the “doneness” of a roast or turkey, to the very fancy ones used in QA laboratories of the world’s food industries and others.
Check out some of these sites below. They may have just what you seek and you’ll come away with a far better appreciation of the range of instruments and capabilities available for science, industry and even your home!
