    Vernier Caliper Wholesale Price List

    Vernier caliper is a measuring tool for measuring length, inner/ outer diameter and depth. The vernier caliper consists of a main ruler and a sliding vernier attached to the main ruler. There are two movable measuring claws on the main ruler and the vernier, namely the inner measuring claw and the outer measuring claw. The inner measuring jaw is usually used to measure the inner diameter, and the outer measuring jaw is usually used to measure the length and outer diameter. Vernier calipers are generally measured in millimeters. There are 4 kinds of minimum reading values: 0.1 mm (10 divisions on the vernier), 0.05 mm (20 divisions on the vernier), 0.02 mm (50 divisions on the vernier), 0.01mm (100 divisions on the vernier). The above-mentioned vernier calipers are available at wholesale prices on, which are shown in the wholesale price list.

    Vernier caliper measurement and reading

    The slide vernier caliper has a higher accuracy than the scale. The reading is divided into two steps. Read the main ruler first and then the secondary ruler. When reading the main ruler, you must pay attention to the reading from the zero scale line, which is similar to the reading of an ordinary ruler and does not need to be estimated.
    To read the secondary ruler, you need to see the total number of grids (precision length) of the result, read the corresponding scale line value, and multiply it by the corresponding length of each grid to get the reading of the secondary ruler. Finally, the data of the main ruler and the sub ruler are added together to obtain the final reading of the vernier caliper, and identify the units.

    Reading example of vernier scale

    As shown in the figure below, on the magnified image we can see that the position of the main ruler opposite to the zero mark is more than 22mm, and the reading of the main ruler is recorded as 22mm. Now look at the secondary ruler, it is a ten-degree ruler, and the unit of each scale is 0.1mm. By observing the scale line, we found that the sixth scale line is aligned with the main ruler scale line, and the reading of the secondary ruler is 0.6mm. Therefore, the reading of the vernier caliper is: 22mm+0.6mm, which is 22.6mm. If the required reading unit is cm, it is read 2.26cm.

    Notice for caliper ruler measurement

    1. The caliper ruler is a more precise measuring tool. It should be handled with care and should not be collided or dropped to the ground. Do not use vernier calipers to measure rough objects to avoid damage to the measuring jaws. Avoid putting the vernier caliper and the cutting tool together to prevent the cutting tool from scratching the surface of the vernier caliper. When not in use, place the vernier caliper in a dry and neutral place, away from acid and alkaline substances to prevent corrosion.
    2. Wipe the vernier caliper clean before measuring, and check whether the two measuring surfaces and the measuring edge of the caliper are straight and undamaged. When the two measuring jaws of the vernier caliper are closely attached, there should be no obvious gap, and the zero mark of the vernier and the main ruler should be aligned with each other. This process is called calibration of the zero position of the vernier caliper.
    3. When moving the ruler frame, the movement should be free and should not be too loose/ tight or shaking. When fixing the ruler frame with fixing screws, the reading of the vernier caliper should not change. When moving the ruler frame, don't forget to loosen the fixing screws, or loose them too much to prevent the screws from falling off.
    4. When measuring parts with vernier calipers, it is not allowed to apply excessive pressure, and the pressure should be such that the two measuring jaws just touch the surface of the part. If the measuring pressure is too large, not only will the measuring jaw bend or wear, but also the measuring jaw will be elastically deformed under pressure, which will make the measured size inaccurate (the outer size is smaller than the actual size, and the inner size is larger than the actual size).
    5. When reading the vernier caliper, the vernier caliper should be held horizontally, in the direction of the light, so that the person's line of sight and the caliper line surface is vertical, so as not to cause reading error due to the skew of the line of sight.
    6. In order to obtain the correct measurement results, you can measure several times. That is to measure in different directions on the same section of the part. For longer parts, measurements should be made at various parts of the full length to obtain a more accurate measurement result.

    How to buy the best vernier caliper?Wholesale price vernier caliper

    1. Application. To understand the purpose of vernier calipers before buying. Generally speaking, vernier calipers can measure dimensions such as length, inner diameter, outer diameter, and depth. Different measurement requirements have different measurement accuracy for vernier calipers.
    2. Material. The materials of vernier calipers generally include stainless steel, carbon steel, plastic carbon fiber, etc. Generally, vernier calipers made of stainless steel and carbon steel are more accurate, but they are not suitable for measuring valuable items or items that are strongly corrosive to steel.
    3. Measuring range. Vernier calipers have multiple measuring ranges, and different measuring ranges will also affect the price of the vernier calipers. Before purchasing, you must first find out the size of the item you need to measure, and then buy a vernier caliper with a range slightly larger than the size of the object to be measured. provides vernier calipers with a variety of ranges at wholesale prices. You can buy 0-6 inch, 0-8 inch and 0-12 inch slide calipers online now.
    4. Display mode. There are two kinds of vernier calipers: Caliper ruler and digital vernier caliper. The price of the caliper ruler is relatively cheaper, and the service life is relatively longer. Digital vernier caliper is more convenient. In addition, digital vernier calipers usually have multiple units that can be switched with each other.
    5. Brand. vernier caliper brand has a long history and has a good reputation on the market. It is recommended to buy our products at this reasonable wholesale price. Don't buy low-quality products for cheap, so as to avoid inaccurate measurement and affect your work.
