Precision Caliper Manufacturer

As a precision caliper manufacturer, below are the intriduction of these two items:

Digital caliper: it has four way measurement (outside, inside, depth and step measurement), resolution is 0.01mm, basic length from 150mm/6", 200mm/8", 300mm/12" longest can up to 3000mm/120", material normally was made of stainless steel, it's very user-friendly with a digital display that provides immediate and easy-to-read measurements. It often come with additional functions like zero-setting, data output, hold, and mm/inch transfer buttons, the applications including mechanical engineering, metalworking, woodworking, and general-purpose measurements, very easy to operate.

Micrometer: nomally it's for small object measurement, size from 0-25mm, 25-50mm, 50-75mm, 75-100mm... micrometer can only measure the outside length and thickness, the accuracy is more higher than the calipers, micrometers have a scale and a thimble with fine graduations, requiring more skill to read accurately. Some micrometers have a ratchet mechanism to ensure consistent measuring force, which helps in achieving accurate readings.

1)Accuracy: If you have very high requirements of the accuracy, such as precision machining, electronic component manufacturing, jewelry……  then digital caliper is recommended. The accuracy of Digital calipers is 0.01mm and can reduce human reading errors. For general handicrafts or daily use which the accuracy requirements are relatively not so high, then vernier caliper may be a better choice. The accuracy is generally 0.02mm or 0.05mm.

2)Use environment: If the caliper is used in a humid or dusty environment, then we suggest to choose a caliper with waterproof or dustproof, such as IP54 and IP67. If the caliper is used in a dim environment, a digital caliper with a backlit display will be more convenient for reading.

3)Brand and price: When selecting a brand, it's important to consider your budget while not compromising on quality and accuracy. Avoid the temptation to buy inexpensive calipers that may lack precision and durability. Conversely, there's no need to blindly pursue high-priced, well-known brands. While these brands are reputable, their premium prices may not always be necessary for your needs. The key is to find a balance between quality and affordability.

Calipers, as measuring tools, have a long history and are backed by mature technology and standardized production and inspection processes. Our factory adheres strictly to these standards, ensuring that each caliper undergoes rigorous quality control to guarantee precision and reliability. We also offer comprehensive after-sales service. Should you encounter any quality issues, feel free to contact us at any time, and we will provide a satisfactory resolution. Additionally, our prices are highly competitive, offering you great value for your investment.

4)Operational convenience: For some people who need to use calipers frequently, the convenience of operation is very important. For example, some digital calipers have functions such as quick zeroing, data saving and output……which are convenient for user. You can choose according to your own needs before purchasing. We have various styles of caliper for you to choose; you also can contact with our salesman to give you professional suggestions.

When moving the caliper frame, do not forget to loosen the locking screw. Do not make it too loose to avoid dropping. When moving the caliper frame, it should move freely without being too loose or too tight, and there should be no shaking. When fixing the caliper frame with a locking screw, the readings of the caliper should not change.

An electronic digital caliper is a precision measuring instrument widely used in manufacturing, engineering, and quality control processes. Here are its key aspects:
 

Measuring Jaws: These are the parts that come into contact with the object being measured. There are usually two types - an outer jaw for measuring external dimensions and an inner jaw for measuring internal dimensions.

Main Scale: It provides a basic framework for measurement. The measuring jaws slide along the main scale.

Digital Display: This is a prominent feature of electronic digital calipers. It clearly shows the measurement value in a digital format, typically with high precision up to 0.01 mm or 0.0005 inches.

Electronic Circuitry: Housed within the caliper, the electronic circuitry is responsible for processing the measurement data. It includes sensors that detect the position of the sliding jaws and convert this mechanical movement into an electrical signal, which translated into a numerical value for display.

Battery Compartment: Electronic digital calipers are powered by small batteries. The battery provides the necessary electrical energy for the operation of the electronic components.

Read the integer part on the main scale: If the "0" graduation line of the scale frame exactly aligns with the 25 mm graduation line on the main scale, then the integer part is 25 mm. If the "0" graduation line is between 25 mm and 26 mm and is closer to 25 mm, the integer part is also taken as 25 mm.

Read the decimal part on the dial: The dial of the dial caliper is used to read the decimal part. The least count (graduation value) of the dials of different dial calipers may vary. Common ones are 0.01 mm, 0.02 mm, and 0.05 mm.

Least count is 0.01 mm: Usually, one full circle of the dial is equally divided into 100 small grids, and each small grid represents 0.01 mm. If the pointer points to the 35th small grid on the dial, then the decimal part is 0.01×35 = 0.35 mm.

Least count is 0.02 mm: Generally, one full circle of the dial is equally divided into 50 small grids, and each grid represents 0.02 mm. When the pointer points to the 20th grid, the decimal part is 0.02×20 = 0.40 mm.

Least count is 0.05 mm: Often, one full circle of the dial is equally divided into 20 small grids, and each small grid represents 0.05 mm. If the pointer stops at the 12th grid, the decimal part is 0.05×12 = 0.60 mm.

Get the final measured value: Add the integer part read from the main scale and the decimal part read from the dial, and this is the measured value of the dial caliper. For example, if the integer part on the main scale is 25 mm and the decimal part on the dial is 0.35 mm, the final measured value is 25 + 0.35 = 25.35 mm.

When reading, ensure that your line of sight is perpendicular to the dial scale to reduce reading errors. If you have doubts about the measurement results, you can take multiple measurements and calculate the average value to improve the measurement accuracy.

1. Familiarize Yourself with the Calipers

Identify the main scale and the vernier scale. The main scale usually has markings representing units such as millimeters or inches. The vernier scale is a secondary scale that allows for more precise readings.

Locate the jaws of the caliper. There are outer jaws for measuring external dimensions (like the diameter of a rod) and inner jaws for measuring internal dimensions (like the diameter of a hole). Also, note the depth probe if your caliper has one, which is used to measure the depth of holes or recesses.

2. Measuring Dimensions

Clean the object you want to measure to ensure accurate readings. Any debris or dirt on the surface can affect the measurement.

Open the outer jaws of the caliper wider than the object's dimension you're about to measure.

Gently close the jaws around the object until they make light contact with the object's surface. Avoid squeezing too hard, as this might deform the object and lead to inaccurate measurements, especially if the object is soft.

3. Read the measurement:

Reading the Main Scale: Note the last visible mark on the main scale that lines up with the vernier scale's zero. This gives you the whole number part of the measurement.

Reading the Vernier Scale: Next, look for the line on the vernier scale that vertically aligns perfectly with a line on the main scale. The divisions on the vernier scale provide the measurement past the decimal point.

Adding the Readings: Finally, add the main scale reading and the vernier scale reading together to obtain the final measurement.
