The accuracy grades for industrial instruments in our country include: 0.005, 0.02, 0.05, 0.1, 0.2, 0.35, 0.4, 0.5, 1.0, 1.5, 2.5, 4.0, etc. The smaller the order, the higher the precision (accuracy). II. Accuracy grades for measuring and indicating instruments used in industrial process measurement and control are: 0.01, 0.02, (0.03), 0.05, 0.1, 0.2, (0.25), (0.3), (0.4), 0.5, 1.0, 1.6, (2.0), 2.5, 4.0, 5.0 ； There are 16 in total; which one is commonly used in chemical engineering design?
The accuracy grades are defined in specific ways; which grades exist and which do not depend on the **measurement verification regulations** for the particular product. . . The regulations are what matter. . . Everything else said doesn’t count; it’s just nonsense.
If you have money, just build it; if you don’t, the precision will be a bit lower.
What instrument is 0.005?
