Commercial, geophysical, meteorological, and general-purpose instruments and equipment is a large segment in the measuring and controlling devices industry.
Through the mid-2000s, the miscellaneous measuring and controlling devices industry was projected to grow at an annual rate of 3 percent.

Exactly what measuring device? There are hundreds of "measuring devices" to measure different things.
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.
Thermistors can be used for temperature sensing and control in devices such as thermostats, air conditioning systems, and refrigerators. They can also be used in medical applications for monitoring body temperature or in automotive applications for measuring engine temperature.

No devices use for measuring in math. In math we cannot measure we just calculate.
Galvanometers were used for measuring small electric currents in early electrical instruments, as well as for detecting the presence and direction of current flow in circuits. They were also used in the development of instruments like voltmeters, ammeters, and other measuring devices in electrical engineering.
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.
A thermometer is commonly used to measure and monitor thermal energy in various systems and environments. It works by detecting changes in temperature and providing a numerical reading for reference. Other devices such as thermocouples and infrared sensors are also used for more specialized applications.

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.
