What is a measuring instrument?
Measuring instruments (also known as measuring instruments) refers to the separate or together with auxiliary devices used to measure the apparatus. Measuring instruments are generally divided into: physical gauge (including "standard substances"), measuring instruments (meters) and measuring devices. 1, according to the "People's Republic of China *** and the State Measurement Law Implementing Rules", Article 61 (a): Measuring instruments can be used to directly or indirectly measure the value of the object being measured devices, instruments, gauges and standard substances used to unify the measurement value, including measuring instruments, measuring instruments and standard substances, including measuring instruments and standard substances, including measuring instruments. Measurement value of the standard substances, including measurement standards, measurement standards, work measuring instruments. 2, physical measurements: such as steel plate ruler, vernier calipers, weights, etc.; 3, measuring instruments (meters): such as energy meters, gas meters, water meters, gasoline dispensers, blood pressure meters, pressure gauges, etc.; 4, measuring devices (usually with auxiliary devices): such as energy meter calibration device, thermocouple calibration device, etc..

What are the measurement devices
This is to be divided into a good variety of it, including: electrical measurement; quantum measurement; chemical measurement and analysis; mechanical measurement; acoustic measurement; optical and radium metrology; length measurement; precision mechanical measurement; measurement of ionizing radiation; medical engineering measurement; thermal measurement; measurement of material properties; information and electronic measurements; bio-measurement; energy measurement; environmental measurement; Engineering Metrology and Inspection. Each type of measurement has different device requirements and accuracy requirements.
Please be precise when asking questions.
What are the categories of measurement devices?
ABC three categories, Class A refers to the mandatory verification of instruments, Class B is the cycle of verification, Class C is a one-time verification.
What is instrumentation measurement?
Instrumentation measurement is to ensure the accuracy of instrumentation, strengthen the instruments and apparatus for regular maintenance and calibration of the meaning.
What are the weighing and measuring devices?
Railroad scales, passing railroad scales, automobile scales, passing automobile scales, crane scales (traction weighing), spring scales, platform scales, disk scales, pole scales, belt scales, and various types of scales.
What are the common measuring devices
What are you talking about upstairs? It's just that the wind and horses are not related to each other. Do not understand that do not explain, so as not to mislead the public, it seems that the popular science is to catch a good deal.
Measurement devices (the exact name is measuring instruments) traceable up to the ancient times said that the weights and measures, and now mainly divided into long, heat, force, electricity and other major categories. Mainly long measuring instruments (such as: steel ruler), hardness tester, thermometer, scales, balances, electric three tables and the corresponding secondary instrumentation. There are many others, not to mention here.
