INSIZE caliper gauge

Professional calipers from insize for all applications


Caliperswhich are also called Calipers or calibers belong to the group of length measuring instruments. There are different designs and variants, each of which is predestined for specific tasks. Among the advantages of Calipers include accuracy, robustness and the numerous possible applications Calipers are needed in many industries. Assemblers use the tools as well as manufacturing companies for quality control or woodworking companies such as carpenters or woodturners.

In the assortment of insize you will find a wide range of different calipers. With these tools you can measure for example outside diameters, Internal grooves, Gap widths, Gears or also Crimp heights measured. Benefit from the experience of insize and order measuring tools from professionals. As the 3rd largest manufacturer of measuring technology, you receive high quality that masters all tasks reliably and precisely in everyday use.

The different types of calipers

The classic caliper has measuring legs with which the distance between two points is measured. Small and medium-sized objects in particular are measured with this tool. As a rule, calipers have two measuring legs. Firstly, a set of outer measuring legs, with which the outer diameter or the distance between two points is measured. Then there are the inner measuring legs. These can be inserted into a pipe or similar object and then measure the inside diameter These calipers are designed for measuring ranges up to 2500 mm.

Furthermore, the calipers differ in the length and shape of the legs. These determine decisively which objects can be measured with the tool. Large, round objects with a corresponding diameter require a caliper with long a caliper with long measuring legs. Small objects, on the other hand, can be handled much better with more compact tools. The length of the legs is usually between 30 and 150 mm. In addition to simple, straight legs, there are also numerous special shapes Calipers with prism legs are intended for odd-numbered grooved workpieces. This makes it easy to measure journals or gears.

The dovetail calipers function according to the same principle. However, they are intended for installation on machine tools and have a maximum measuring range of up to 1000 mm. These tools are used to take horizontal or vertical measurements. They can be mounted on lathes or milling machines, for example, to facilitate the positioning of workpieces or to measure traverse paths.

There are also very special calipers for many industries and tasks. For example the Clock calipers. These are particularly fine tools that are designed for small measurements. The devices have measuring ranges of up to 150 or 300 mm. For precision mechanics or goldsmiths there are even smaller calipers Calipers for jewellery are designed for measurements between 0.1 and 25 mm. In this range, the tools work particularly precisely, as the measuring accuracy is up to 0.02 mm.

Depth calipers represent another special form of caliper gauge. They measure the depth at a certain point in relation to the surrounding height with the help of a thin measuring probe. Depth calipers are intended, for example, for boreholes or internal grooves. The various models of depth calipers are designed for measuring ranges between 25 and 1000 mm.

Analogue or digital calipers

There are two technologies for calipers, which have different characteristics in practice. The traditional calipers have a verniera scale on which the measured values are read. In addition, there are now Calipers with digital display are widespread. Here, all measured values are shown on a display, which makes reading easier. However, the mode of operation during measurement remains the same, as the measuring legs continue to be moved mechanically. The advantage of analogue calipers is their robustness. These tools are automatically waterproof, as there is no sensitive technology. However, there are also digital gauges that are waterproof and protected against dust according to ip 67 or other standards. Here again the advantages of high quality calipers of the brand insize. Digital tools are usually not waterproof and can therefore not be used in adverse environmental conditions. With the waterproof calipers from insize you do not have to do without the advantages of digital technology in these scenarios.

The analog calipers are also ready to use anytime, anywhere. The digital models require a power source, with small button cells also ensuring that the tools are ready for mobile use. Many digital calipers from insize have a data output. This interface enables a direct connection to a computer with the help of optionally available accessories. There are cables with different interfaces and WLAN modules, so that there are various possibilities for establishing a connection. Via the data interface, the read-out values can be transferred directly to a computer system for further use.

Precise measurements and options for measuring tasks

The biggest differences between calipers can be seen in their accuracy. Inexpensive tools often show deviations of half a millimeter or more in measurements. This may be tolerable for some operations or in the hobby sector, but is not acceptable in a professional environment. For this reason the calipers in the insize range are designed for very precise measurements. Due to the high quality of workmanship and strict controls, measuring accuracies of up to +/- 0.02 mm can be achieved. Thus, the calipers from insize are a good choice when particularly precise measurement data is required Precise calipers are able, for example, to quickly identify the thickness of a veneer or to precisely identify a standard.

It is also important for measuring work that the values are easy to read. For this reason, the resolution of digital displays is 0.01 mm. Furthermore, the calipers with display can be switched between mm and inch at the push of a button. Thus, measurements in both standards can be carried out with one tool without any problems. Furthermore, the digital technology offers the possibility to work with preset measuring values, to carry out absolute or incremental measurements or to set the current measurement to zero. In this way, serial measurements and other complex measuring tasks are possible without additional accessories.

Extending the range of applications with accessories

A wide range of accessories is available for insize calipers. This considerably extends the functionality of the measuring tools and allows an individualization of the fields of application. The accessories include for example exchangeable measuring inserts. There are, for example, round, spherical, conical, flat as well as plate- or bush-shaped inserts. With the aid of additional jaws, which are mounted on the measuring legs, this individual equipment can be realised without any problems. In this way it is possible to equip the measuring legs with completely individual measuring tips. In this way, even on very special objects, exactly the measurements that are required can be carried out. This option is another quality feature of a high-quality tool.

High quality calipers from insize

Tools, especially those intended for measuring tasks, have to meet certain requirements. Here, it is mainly a question of quality. Calipers from insize are designed with high requirements in mind insize is the 3rd largest manufacturer in the field of measuring technology and has accordingly extensive experience in the production of tools The target group are mainly professional, commercial and industrial users who have high demands on precision when measuring.

For calipers, the focus is on precision as well as robustness. The quality of the measuring tools can be easily determined with a simple test. For example, the measuring legs are completely closed and then checked to see whether a light gap can be seen when the tool is held in front of a light source. If no light gap can be seen, this means that the measuring legs do not allow any light to pass through and are therefore perfectly flat. This precision in manufacturing guarantees a high degree of accuracy, as deviations in the measurement are prevented. Cheaper tools can show variations here. Thus it can happen that one and the same tool emits different measurement data, depending on the position of the object between the measuring legs. If high precision and exact measurement data are required, such deviations are of course unacceptable.

In practice, the handling of the tool is also crucial The caliper gauges from insize are precisely manufacturedso that the legs are smooth-running and do not hook. Various models also have a fine adjustment feature. This thumb roller allows a slow approach to the object or a very fine adjustment of the measuring legs.

Another decisive factor is the material of the calipers. The tools from insize are mostly made of stainless steel. Stainless steel guarantees that the tool is durable, rust-free and long-lasting. Some models are made of plastic or ceramic. For special applications these calipers are needed and offer special features. Thus ceramic-tipped measuring surfaces non-magnetic, non-conductive and at the same time completely abrasion resistant.
