A caliper is a specialized measuring instrument, capable of measuring the length, width, height, or diameter of objects. There are many different types of calipers, depending on the purpose of use and the required accuracy. Some common types of calipers are: electronic calipers, mechanical calipers, external calipers, internal calipers, depth calipers, three-legged calipers… Calipers are widely used in most applications. fields such as mechanics, electronics, construction, …


A Micrometer is a device widely used to accurately measure details in the field of mechanical processing and machine manufacturing. Micrometer is considered a measuring device with many advantages and provides higher accuracy than other basic measuring devices. There are many different types of micrometers, depending on the purpose of use and the required accuracy such as: external micrometer, internal micrometer, electronic micrometer, …


Dial indicator is a measuring device used very commonly in the precision mechanical industry. It can be attached to the head of a height gauge to measure the straightness, direction reversal, or parallelism of any part. In addition, the dial indicator can also be combined with a number of other measuring tools depending on the need to measure the dimensional parameters of the machined parts. The dial indicator has very high sensitivity and accuracy from 0.01mm to 0.001mm.


The gauge block is rectangular in shape with two opposite sides flat and parallel, machined with precision and very high surface gloss. Standard gauge block sets usually include many blocks of different sizes contained in a box. The gauge block is often used to measure slots on precision mechanical workpieces or is also commonly used as a reference tool in checking the accuracy of length-measuring tools such as calipers, micrometers, dial indicators, …


The Ring Gauge is a standard measuring tool with an extremely precisely machined inner hole with a very high surface finish, in different sizes to serve measuring needs. Diversity inspection in mechanical detail processing activities. Ring gauges are often used to quickly check the accuracy of the outer diameter of cylindrical and cylindrical parts after machining. In addition, the ring gauge is also used to check the accuracy of a number of measuring devices such as: circularity meter, profile meter, internal micrometer, …


The Pin Gauge, also known as the Standard Cylindrical Measuring Block, is a precisely machined circular cylindrical tool. The pin gauge is used to measure and check the diameter of the small holes of the part after machining. It is also used as a standard tool to check the accuracy of other measuring tools such as a Micrometer, Caliper,…


Tape measure, also known as steel tape measure, is made of stainless steel or alloy. Inside the ruler, there is a spring, with good elasticity to help the user extend the ruler. Tape measures are often commonly used in construction, garments, or measuring and measuring common items.


It is an extremely popular length-measuring tool. Ruler with graduations, accurate to millimeters. Mainly used to measure length, height, etc.


Laser distance meter measures distances between two points with speed and precision. The start point of the measurement is the set measurement edge of the laser distance meter and the second point is the end point of the beam. The maximum range varies depending on the device and can extend to over 100 m. Digital distance measurement offers many advantages over conventional measuring using a folding rule or measuring tape. Distances can be measured precisely and conveniently in just a few seconds. In addition, depending on the model, the devices can calculate areas and volumes of space at the touch of a button, function using a touchscreen, and have integrated Bluetooth and camera functionalities and an integrated tilt sensor.


The 2-dimensional Video Measuring Machine is a 2D profile measuring device that combines the technology of determining coordinates using an optical ruler, a high-resolution camera, and image recognition software to measure all kinds of dimensions.

The product is placed on the sample stage and moved with lead screws. The optical ruler attached to the sample stage will provide coordinate parameters for moving on the axes, the software will combine the coordinates and images to provide the dimensions to be measured.

2D VMM is suitable for 2D projection and cross-section measurements of products. Can continuously measure many types of dimensions and display them visually on the screen, then export the results into Excel, Word, PDF, or .dxf files. This is an advantage that traditional measuring tools such as calipers, micrometers, sample guides, etc. cannot provide.


The 3-dimensional Coordinates Measuring Machine is a measuring device that operates on the principle of using a probe that touches the product surface. Combine with measurement software to check dimensions.
Measurement results on the 3D CMM machine have very high accuracy (about 2 ~ 3 microns). Depending on the machine model, the probe position can be controlled manually by the operator or can be controlled by a computer and CNC systems.

Users can set up automated testing procedures on computer-controlled CMMs in situations where mass production sample inspection is required.


Profile measurement systems measure and record the profile of a target by tracing the surface of the target using a stylus. Some instruments can even be used as surface roughness meters. Models with computer numerical control (CNC) are capable of measuring the angles, radii of arcs, height differences, and screw thread pitches. These instruments are ideal for measuring minute shapes such as screw threads and thin films in the order of micrometers.
In recent years, profilometer models have been developed that use a laser instead of a stylus to measure complex shapes by tracing the profile in a non-contact manner. Some models are even able to perform measurements of both the top and bottom surfaces.
These instruments are mostly used in the creation of prototypes to check whether the specifications match the design drawings. They are also applied in reverse engineering.


Roughness is an important parameter when trying to find out whether a surface is suitable for a certain purpose. Rough surfaces often wear out more quickly than smoother surfaces. Rougher surfaces are normally more vulnerable to corrosion and cracks, but they can also aid in adhesion.
A roughness tester is used to quickly and accurately determine the surface texture or surface roughness of a material. A roughness tester shows the measured roughness depth (Rz) as well as the mean roughness value (Ra) in micrometers or microns (µm
