Advantages of Caliper

 
金属数显卡尺
 

Accuracy and precision

The first advantage of calipers is that they provide accurate and precise readings.

 

Durability

Since the calipers are made with strong materials such as stainless steel, they have long tool life.

Versatility

Calipers are versatile instruments which can be used for a variety of purposes. They are typically used for internal, external, and depth measurement.

 

No extra scale needed

The measurement on a caliper can be read directly due to its fixed and movable scale. They do not require a separate scale to take measurements.

Parts of a caliper

 

The main parts of the caliper are as follows:

Application Of Caliper

 

Automotive Industry: In the automotive industry, calipers are essential for ensuring the accurate dimensions of engine components, brake parts, and other critical elements.

 

Aerospace sector: The aerospace sector relies on calipers to measure parts with exacting standards, such as turbine blades and airframe components, where precision is vital for safety and performance.

 

Manufacturing industry: In the manufacturing industry, calipers are used for quality control, ensuring that products meet stringent specifications, whether in metalworking, plastics, or electronics.

 

Woodworking: Calipers are indispensable in sectors like woodworking, where they help ensure the precise fitting of components.

 

Medical device industry: Calipers In the medical device industry, accuracy is critical to the functionality of surgical instruments and implants.

 

Educational: In educational institutions, calipers are used as teaching tools in physics, engineering, and technical courses.

 

Home improvement: When decorating a house or installing furniture, the use of the caliper can help measure the size of the space to ensure that furniture and decorations are the right size.

 

Key Differences Between Dial, Digital, and Vernier Calipers

 
 
01
 

Readings

Reading a Vernier caliper takes some practice, as the decimal numbers need to be derived from the Vernier scale. Dial calipers are somewhat easier, as the decimal numbers are instantly shown on the dial and added to the whole number read on the sliding scale. Digital calipers offer the easiest and fastest reading, as the display instantly shows the reading.

 
02
 

Ease Of Use

Vernier calipers are by far the hardest to use due to their readings and are nearly impossible to adequately calibrate once a zero-point error occurs. On the other hand, both Dial and Digital are pretty straightforward to calibrate to zero, though digital calipers are generally easier to use due to their instantaneous readings from a single scale (in this case, an LCD display).

 
03
 

Use Conditions

Vernier calipers for the win in this category, as they’re effective in almost any conditions, aren’t affected by magnetic fields, and are mildly shockproof since they don’t have intricate moving parts as dial calipers do. The same can be said for digital calipers, though they are sensitive to magnetic fields, water, dirt, and oil and require a power source (a battery) to function. Dial calipers stand in the middle between the two. They’re resistant to water, dirt, and oils but are very sensitive to magnetic fields and shocks.

Caliper Usage Requirements

 
01/

Before using your calipers, quickly check to make sure there’s no sawdust or other gunk keeping them from fully closing.

02/

To get the most accurate reading, don’t over tighten the caliper jaws, or push too hard on the depth rod or reference edge.

03/

Avoid colliding with hard objects or falling on the stool or floor to damage the calipers.

04/

Do not expose the caliper to excessive heat, humidity, or magnetic fields that could affect its accuracy.

05/

Please make sure that the caliper is in close contact with the object to be measured so that it is perpendicular to the object to be measured.

06/

Keep the caliper in a protective case in a dry and clean environment to extend its lifespan and ensure consistent performance.

FAQ

 

Q: Are you a trading company or a manufacturer?

A: In order to control the quality and offer better service to our customers, we established our own factory in 2012.

Q: How can you ensure the quality?

A: We test the prototype sample before development, we do user’s test, abnormal test, durability test before mass production, Strict visual inspection is applied to reject any slight scratch even on non-measuring surface. we make full inspection on every finished product before shipment.

Q: What should I do if the product has quality problems?

A: Please contact with us freely if has quality problem. We offer after-sales service and will solve your problem in 48-hours.

Q: How much will the shipping charges be?

A: It depends on the shipping method. Please note us your destination and the required method, by air or by sea or by express. Then we will give you the shipping solution and freight cost and shipping time.

Q: Can I get free samples?

A: We have to charge both samples and freight cost, and when you place orders, we'll refund your sample cost. Or we can provide free samples to you with freight collect.

Q: What is the difference between high quality and low quality caliper?

A: High quality: Higher hardness stainless steel, better surface-finish, sliding smoothly and more wear resistance, longer service life, not easy to rusting.(more suitable for professional industry measurement).
Low quality: carbon steel #50, surface-finish is not good as high quality one, easy to rusting, Sliding roughness, wear resistance, but price is cheaper (it's more for household, personal use, DIY market).

As one of the most professional caliper manufacturers and suppliers in China, we're featured by quality products and good service. Please rest assured to wholesale customized caliper made in China here from our factory.
