Pyrometry

Pyrometry is a technique used to measure the temperature of objects, especially very hot ones, without direct contact. It relies on detecting the thermal radiation emitted by an object—like the glow of a furnace or molten metal—and analyzing this radiation to determine temperature. Different methods include optical pyrometry, which uses the emitted light's color, and radiation pyrometry, which measures the intensity of emitted energy. This approach is essential in industries like metallurgy and ceramics, where direct contact thermometers can't withstand extreme heat, allowing accurate temperature readings in high-temperature environments.
