to make accurate and precise measurements, so that we can compare stuff accurately on a scale, instead of saying that this apple is bigger, with a weighing scale, we can say that Apple x is 15g while Apple y is 20g so Apple y is heavier.
Devices used in measuring potential hazards include gas detectors for detecting toxic gases, radiation detectors for measuring radiation levels, and pH meters for assessing chemical hazards. Other devices include dosimeters for measuring exposure to radiation, infrared cameras for detecting hot spots, and noise dosimeters for measuring noise levels.
Laser measuring devices are used to accurately and quickly measure distance, length, area, and volume in various applications such as construction, interior design, real estate, and DIY projects. They provide precise measurements by emitting a laser beam and calculating the distance based on the time it takes for the beam to hit the target and reflect back.
Some of the earliest measuring devices used by humans were cubit rods, which were sticks of a standard length used for measuring dimensions, and balances, which were used to measure weight by comparing objects against known weights. These tools have been used by ancient civilizations such as the Egyptians and Mesopotamians.
Laser-ranging devices us laser beams to detect the fault movements that cause earthquakes.
No, a psychrometer is utilized to measure the relative humidity in the air by comparing the readings between a dry-bulb thermometer and a wet-bulb thermometer. Wind speed is typically measured using anemometers or other wind-measuring devices.
They help you to measure things.
measuring devices different according to the parameter you want to measure. weight is measure using weighing balance temperature is measure using a thermometer, or thermistor. length is measured using ruler. and so on
Exactly what measuring device? There are hundreds of "measuring devices" to measure different things.

No devices use for measuring in math. In math we cannot measure we just calculate.

There are any measuring devices available, your question should be little specific. Measuring device is for electricity or water or earth quake or data traffic or air pressure.
Commercial, geophysical, meteorological, and general-purpose instruments and equipment is a large segment in the measuring and controlling devices industry.

Most pressure measuring devices have elastic members for sensing pressure at the primary stage elastic members are of many types and convert the pressure into mechanical displacement which is later converted into an electrical form using a secondary transducer.These devices are known as force summing devices
