Hardware measuring instruments can be said to be indispensable and important equipment in the hardware processing industry, which can be used to measure the size and shape of various hardware products, help hardware processing personnel accurately grasp the size and performance of products, and help improve product quality and manufacturing efficiency. So what are the types of hardware measuring instruments? Let's take a look at this article to introduce it to you.
What are the types of hardware measuring instruments and their - What are the types of hardware measuring instruments and their uses?
1. Vernier calipers
Vernier caliper is one of the most common hardware measuring instruments, it is mainly used to measure the length, width and height of straight lines, can be said to be one of the most basic tools in hardware processing factories. The vernier caliper is usually composed of two discs and a measuring rod, and its accuracy is very high, which can reach 0.02mm, which is suitable for the measurement of various hardware products.

2. Outer diameter caliper
The outer diameter caliper is mainly used to measure the outer diameter size of cylindrical and round parts, and is suitable for the production and inspection of many parts in the hardware processing industry. Compared to the vernier caliper, the structure of the outer diameter caliper is simpler, but its accuracy is still very high, usually up to 0.01mm.

3. Inner diameter caliper
The inner diameter caliper is an instrument specially used to measure the size of the inner diameter, which is mainly suitable for measuring the internal size of workpieces such as round holes and grooves. The inner diameter caliper usually consists of two measuring jaw arms and a measuring rod, and its accuracy is generally higher than that of the outer diameter caliper, which can reach 0.005mm.

4. Right angle plate
Right angle plate, also known as angle plate, is a tool used to measure right angles and check the amount of straight angle of workpieces. The shape of the right angle plate is usually L-shaped or T-shaped, and its edge flatness is high, and the accuracy can reach 0.01mm. Right angle plates are mainly used to inspect and correct the amount of straight angle of hardware products to ensure that the size and geometry of the product meet the specified standards.
5. Tape measure
The tape measure is a common measuring tool and is usually used for the measurement of larger parts, such as steel plates, pipe fittings, etc. The tape measure is usually composed of a tape reel, a measuring belt and a tape measure mandrel, and its size is generally 3m, 5m, 8m, etc. The accuracy of the tape measure is generally low, usually between 0.2-0.5mm, but its measurement range is very wide, and it is one of the indispensable measuring tools in the hardware processing industry.
6. Surface roughness meter
Surface roughness meter is a kind of equipment used to measure surface roughness, which can be used to measure the flatness, smoothness and burr degree of the surface of hardware products. Surface roughness meter is usually composed of measuring head, measuring rod and display instrument, and its accuracy can reach 0.001μm, which is one of the representatives of high-end hardware measuring instruments.

7. Desktop projector
Desktop projector is a kind of equipment that projects workpieces on the screen or wall for magnified observation, which is widely used in workpiece inspection and quality control in the hardware processing industry. Projectors usually have the characteristics of high magnification, high measurement accuracy, wide dimensional measurement range, etc., and their structure is complex, but powerful, and can clearly display and measure and analyze various irregular shapes and defects on the surface of the workpiece.
