A pyrometer is type of remote-sensing radiation thermometer which is used to measure the high temperature.It is based on Stefan-Boltzmann law which describe that the total radiation emitted by the black body is proportional to the fourth power of its temperature (E∝T∧4). It is used to measure the temperature of distant object such as sun.
A pyrometer is type of remote-sensing radiation thermometer which is used to measure the high temperature.It is used especially for the measurement of moving objects or any surface that cannot be reached or cannot be touched. The temperature is measured by measuring the thermal radiation.
Pyrometer is used to measure temperature above 1500°C.
Mainly there are two types of devices which is used to measure solar radiation these are : 'Pyrheliometer' and pyranometer
Manometer is an instrument that uses a column of a liquid to measure pressure of liquids or gases commonly referred as pressure measuring instrument.

An ammeter is used to measure the electric current in a circuit.A hygrometer is used to measure the moisture content.A spring balance is a weighing apparatus that measure weighs by the tension of a spring.A barometer is used to measure atmospheric pressure.
An ammeter is used to measure the electric current in a circuit not for measuring electric power.Thus, option (d) is not correctly matched.
A barometer is a scientific instrument used in meteorology to measure atmospheric pressure.A sudden fall of mercury in a barometer indicates the thunderstorms.
