An instrument for measuring high degrees of heat, beyond the capacity of a mercury or gas thermometer.
[pyro- + G. metron, measure]


(pī-rŏm′ĕ-tĕr) [″ + metron, measure]
A device for measuring a very high temperature.

pyrometer (pīrom´ətur),

n an instrument for measuring temperature by the change of electrical resistance within a thermocouple. It is a millivoltometer calibrated in degrees of temperature.


instrument for measuring the intensity of heat when this is beyond the range of the mercury thermometer.
