Classification of Precision Instruments from the Perspective of Measuring Objects

According to the different measurement objects, precision instruments can be divided into the following categories:

Geometric precision instruments: such as vertical angle measuring instruments, laser interferometers, coordinate measuring machines, etc.

Thermal precision instruments: such as various barometers, vacuum gauges, multi wavelength temperature measuring instruments, etc.

Mechanical precision instruments: such as force measuring instruments, strain gauges, acceleration and velocity measuring instruments, etc.

Time and frequency precision instruments: such as timing instruments, atomic clocks, etc.

Electromagnetic precision instruments: such as ammeters, voltmeters, power meters, etc.

Wireless precision instruments: such as oscilloscopes, signal generators, etc.

Optical and acoustic precision instruments: such as spectrometers, photometers, noise measuring instruments, etc.

Ionizing radiation precision instruments: such as radioactive measuring instruments, etc.


These precision instruments play an irreplaceable role in their respective fields, driving technological progress and social development.
