    Technician B says that a thermometer measures temperature.

    A thermometer is a type of device which is used to measure temperature. It consists of a sensor (also called bulb) to which a glass tube is attached. The glass tube contains mercury. Because of its high coefficient of expansion, the mercury expands when heated for the slightest increase in temperature and contracts for the slightest decrease in temperature. The increase or decrease in mercury level corresponding to the temperature rise or fall is marked alongside the glass tube.

    A pyrometer is a type of device used for measurement of relatively higher temperature as compared to a thermometer. In cases of higher temperature viz...
