• Shape A1

This design is commonly referred to as a pocket vernier caliper. It has a locking screw and can be used to measure internal, external and depth dimensions up to a size of 160 mm.

• Shape B

In contrast to other forms such as cutting edges, this form of the measuring gauge has shaped measuring surfaces, which is particularly useful for measuring external dimensions, shapes and grooves. This form is also known as a toolmaker's measuring gauge, named after the craft of cutting tool construction.

• Shape C

This shape is the best for depth measurements because the bridge available as a measuring surface is only suitable for this. Internal and external dimensions cannot be measured with it, which is why it is only suitable for this special application.

• Shape E

Form E denotes the workshop measuring gauge. It can be used to carry out internal and external measurements. The shape is characterized by combined measuring surfaces. Internal and external measurements are carried out with the same legs.

• Form D

It is almost identical to Form E, but also has crossing sensors for measuring internal dimensions> 10 mm (smaller internal dimensions are only possible with Form A).

• The outside measurement

The outside measuring legs are located on the underside of the digital measuring gauge. The workpiece to be measured is inserted as far as possible between the legs. The legs should lie tightly against the tool; any tilting should be avoided, which could otherwise lead to measurement errors.

• The inside measurement

The inside measuring legs are located on the top of the caliper. These are also called cross beaks and are used to measure holes or grooves. First attach the fixed leg and then the movable leg up to the stop.

• The depth measurement

With the depth measuring rod, which is located at the rear end of the digital caliper, you can determine the depth of boreholes. Make sure that the rod is inserted exactly at a 90 degree angle.

• The step measurement

The measurement is similar to the depth measurement, only that the caliper is used on the face for this purpose. Here the moving part is put on and the fixed part becomes the moving part.

• Which material should you choose?

Here you only have the choice between plastic and steel. If you only need your vernier caliper occasionally, you can use plastic, but the price for a steel version is not significantly more expensive. Hence ours digital caliper buy recommendation: Buy yourself a metal caliper right away.

• Which shape is the right one?

You have to decide which measuring gauge is the most suitable for you based on the shape. The form A1 is most common for the hobby craftsman, followed by E and D.

• Which degree of protection is important?

Digital calipers are offered with a high degree of protection, which should be at least IP 54, better still IP 67. This is particularly important for the LED displays, because moisture is poison for them Electronics and determines its lifespan.

• What should a caliper weigh?

Anyone who works a lot with it will of course appreciate a lightweight. However, a slightly heavier model is easier to hold.

• Which batteries are needed?

Fortunately, almost all digital calipers are delivered with a battery, mostly with a spare battery and packed in a box.

• Where can I buy a digital caliper?

Vernier calipers can be bought in hardware stores or tool shops. But you can also use yours Order digital caliper online or buy. At the same time, you can still use the digital caliper experiences other users benefit.
