A pyrometer is a type of thermometer used for measuring high temperatures, typically above 500°C (932°F). They usually work by sensing the thermal radiation emitted by the object, allowing for non-contact temperature measurement. Atmospheric pressure is measured by a barometer, humidity by a hygrometer, and density by a densitometer or hydrometer.
