Galileo thermometers do not freeze. However, you might want to keep it away from absorbing direct sunlight. This can fade the color of the spheres inside the tube, affecting its temperature measuring accuracy. Lots More Information Related HowStuffWorks Articles How Pop-Up Turkey Timers Work How...
Infrared thermometers are divided into fixed thermometers and hand-held thermometers. They are a kind of thermometer that detects the amount of infrared rays on the surface of an object to achieve temperature measurement. How does an Infrared Thermometer work?
Here’s a closer look at how smart thermometers work, how they can streamline your heating and cooling needs, and how they can save you money. How does a thermostat work? Image used with permission by copyright holder Thermostats control how hot or cold your home gets. Before we explain th...
Laser thermometers are actually infrared thermometers. The laser simply provides a means to aim the thermometer. The molecules that make up objects are vibrating constantly; the hotter the molecule is, the faster it vibrates, producing invisible light in the form of infrared energy. Infrared (IR)...

How Does A Thermometer Work Many commercial thermometers contain alcohol because alcohol has a low freezing point. As the temperature of the alcohol increases, it expands and causes the level within the thermometer to rise. The level of the alcohol corresponds to the printed lines/numbers on a ...

How Does a Thermistor Work The working principle of a thermistor is that its resistance is dependent on its temperature. We can measure the resistance of a thermistor using anohmmeter. By understanding how temperature changes affect a thermistor’s resistance, we can measure its resistance to de...
How exactly do they work? Let's take a closer look!Photo: Forehead strip thermometers like this are printed with thermochromic chemicals (liquid crystals) that change color with temperature to reveal whether someone's suffering from a fever (if their temperature exceeds normal body temperature of ...
The simplest kind of barometer is a tall closed tube standing upside down in a bath of mercury (a dense liquid metal at room temperature) so the liquid rises partly up the tube a bit like it does in a thermometer. We use mercury in barometers because it's more convenient than using ...
