[ Focus on Chemical Machinery Equipment Network ] Metrology is the use of technology and legal means to achieve unity and accurate and reliable measurement.
Many aspects of our lives are inseparable from the development of metrology.
From the ancient planning of all things, the measurement of the grandeur of the world and the measurement of the world, the measurement of all things, and the fairness to the development and production of modern multiple confidential measuring instruments, measurement is of very important significance.
Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipmentMany aspects of our lives are inseparable from the development of metrology.
From the ancient planning of all things, the measurement of the grandeur of the world and the measurement of the world, the measurement of all things, and the fairness to the development and production of modern multiple confidential measuring instruments, measurement is of very important significance.
Measuring instruments refer to devices, instruments , measuring tools and standard materials that can be used to directly or indirectly measure the value of the measured object .
Measuring instruments are widely used in various aspects such as production, scientific research and people's lives, and occupy a very important position in the entire measurement legislation.
Because of the unification of national measurement values, it is first reflected in the accuracy and consistency of measuring instruments.
Measuring instruments are not only the main objects of supervision and management, but also the technical basis for providing measurement guarantees.

Today, the editor will take you to recall the past, look at the present, and show the future of measuring instruments.
Recall the past and appreciate the "beauty" of ancient measuring instruments
Recall the past and appreciate the "beauty" of ancient measuring instruments In ancient times, measurement played an extraordinary role.
According to historical records, in the six years of the Western Zhou Dynasty, “the princes of the Zhougong Dynasty were in the Mingtang, making rituals and music, giving measurements, and the world served them.
" "Guanzi·Mingfa Jie" said: "The master of the Ming Dynasty is a metric, an instrument and sticks.
Therefore, the order is followed by the people.
" "The Analects of Confucius Yao Yue": "Respect power and measure, review the law, revise and abolish officials, and act in all directions.
" All these indicate the important political and economic significance of measurement.

1 Dendrobium = 10 buckets, 1 bucket = 10 liters, 1 liter = 10 packs, 1 pack = 2 packs, 1 packs = 5 packs, 1 pinch = 4 packs.

With the use of various * instruments, these ancient measurements Conversion units are used less and less.
In ancient times, measurement had an extraordinary meaning in people’s lives.
People used creative thinking and clever hands to create sophisticated instruments to explore the world, and at the same time integrate heaven, earth, astrology, etc.
Various cultures affect all aspects of people's lives.

Whether it is the exquisite distance measuring instrument in or before the Jin Dynasty-Jili Guche; or the cultural connotation weighing instrument-steelyard; the commonly used capacity instrument for grain-liter and bucket; all show our ancestors and ancestors for generations.
Use their labor wisdom to create practical measuring instruments to make life more convenient, adding a strong ink to the development of measuring instruments.

Nowadays, with the continuous advancement of technology and the continuous exchanges between countries around the world, these ancient metrology have slowly developed into the current metrology instruments, and the metrology standards between countries are also constantly being unified.
Let's take a look at modern measuring instruments again, shall we?

Existing measurement majors such as length, mechanics, heat, electromagnetics, radio, time frequency, ionizing radiation, etc.
; in addition, measuring instruments refer to measuring instruments that are about to convert the measured quantity into directly observable index value equivalent information, such as Pressure gauges , flow meters, thermometers, ammeters, voltmeters.
Electroencephalogram, etc.
; measuring device is the overall combination of measuring instruments and auxiliary equipment necessary to determine the measured value, such as mileage meter verification device, high-frequency microwave power meter calibration device, etc.

In addition, measurement is closely related to the lives of each of us.
Whether it is the electronic scales used in the market, water, electricity, gas meters, and taxi taximeters, they are inseparable from measurement.
From the empirical measurement in the agricultural society, to the experimental measurement in the industrial society, to the measurement in the modern society, measurement has always resonated and developed in the same direction with the progress of the times.

In recent years, with the advent of computer information age, instrument measurement technology has also been continuously developed and improved, and it has gradually evolved from traditional manual measurement to modern automated measurement.
The realization of automated measurement is the only way for the future development of the measurement industry.
Modern automated measurement is to connect the calibration source and the instrument to be calibrated through communication cables such as GPIB, USB, etc.
, and use computer software to realize real-time information interaction between measurement instruments and equipment, and realize one-key automated measurement.

It can be seen from the above that the measurement instrument has been continuously improving from the ancient times to the present, and the measurement culture is also continuously inherited and developed.
By strengthening the carrier construction of the measurement culture to popularize the measurement culture, the measurement can better approach people and promote the process of measurement.

Show the future, the quantum metrology revolution is coming
Show the future, the quantum metrology revolution is coming Industry experts said that the future of metrology will be a revolution in quantum metrology.
Experts said, "In the future, all standards for measurement will be packaged on a chip.
This chip has a basic standard layer, a photonics layer, a laser layer, and all standards such as time, pressure, flow, length, displacement, current, and voltage.
Value.
As long as you have this base standard chip and plug it into the measuring instrument, you can realize that each measurement is accompanied by a calibration.
This will be a break in the measurement system, which will bring the measuring instrument and the standard value The tremendous changes in the world, this change will be realized in the next 15 years.

Dr.
Duan Yuning said at the 2020 China Internet of Things Metrology Innovation Development Forum: “After the arrival of Metrology 3.
0, traditional metrology will change from traditional laboratory measurement to online measurement, from static calibration to dynamic real-time calibration, and from single parameter calibration to multi-parameter calibration.
Coupling calibration, the change from independent instrument and equipment measurement to system comprehensive measurement calibration.
