Temperature Gauge Types of temperature gauges: Analog temperature gauges: These gauges use a mechanical pointer to indicate the temperature on a dial. They are typically used in industrial applications, such as monitoring the temperature of a boiler or furnace. Digital temperature gauges: These gauges use a digital display to show the temperature. They are often used in homes and offices, as well as in industrial applications. Infrared thermometers: These gauges measure temperature by detecting infrared radiation emitted by an object. They are often used in applications where it is difficult or dangerous to touch the object being measured, such as measuring the temperature of a hot furnace or a moving object.
