What is the difference between measuring tools and quantities

A gauge is a type of measuring tool, which is a non-standard measuring tool specifically designed for a certain detection characteristic. It can only be used to detect this characteristic. Measuring tools include gauges, which have universal functions. Some gauges are just one type of measuring tool.

Inspection tool:

Gauge is a simple tool used by industrial production enterprises to control various dimensions of products (such as aperture, spatial dimensions, etc.), improve production efficiency and control quality. It is suitable for mass-produced products, such as automotive parts, to replace measuring tools such as smooth plug gauges, threaded plug gauges, outer diameter calipers, etc.

Measuring tools:

Measuring tool is the abbreviation for physical measuring tool, which is an instrument with a fixed form used to reproduce or provide a given quantity of one or more known values. For example, weights, standard batteries, color temperature lamps, resistors, measuring blocks, signal generators, and measuring instruments (single or multi value, with or without scales) are all measuring tools.

Usage and classification:

1. Standard measuring tools

A measuring tool used as a measuring or calibration standard. Such as measuring blocks, polyhedral prisms, surface roughness comparison blocks, etc.

2. General measuring tools

Generally refers to universal measuring tools manufactured uniformly by a measuring tool factory. Such as rulers, tablets, angle blocks, calipers, etc.

3. Measuring tools

Also known as non-standard measuring tools. A measuring tool specifically designed and manufactured for detecting a certain technical parameter of a workpiece. Measuring tools such as internal and external groove calipers, wire rope calipers, and step gauges are measuring instruments that reproduce measurement values in a fixed form.
