How to distinguish the quality of the rally instrument?

Haida instrument teaches you how to distinguish the quality of the rally instrument? There are many kinds of rally machines on the market. Every one says that it is a manufacturer and the price is different. How do you choose it? Based on many years of experience, Haida engineers sum up the following points to determine the quality of tensile devices, as follows:

First, whether the rally meter meets the standard
1, through the relevant certification, such as QS certification to meet national standards;
2. The series of tensile machines produced by Dongguan Haida Instrument comply with the national implementation guidelines, national standards and military standard standards;
3, Dongguan Haida instrument is the first wholesale company to manufacture measuring instruments permit the company.

Second, Rally instrument quality configuration
1, commonly used ball screw, trapezoidal screw, general screw;
2, the highest accuracy of ball screw;
3, the computer servo system with the operation, the performance of extraordinary performance;
4, gear transmission, more expensive, for high precision;
5, chain drive, cheaper, for low precision;
6, Dongguan Haida instruments generally use high-quality configuration of ball screw and gear transmission.

Third, tension gauge fixture configuration
1, the fixture structure is very special, for the sample, it is very important;
2. Whether the clamping is reliable and there can be no slip phenomenon;
3, during the test, the sample breakpoint is good;
4. Small data discrepancies;
5, whether the fixture is easy to use and safe;
6, large batch, high-frequency test requires the use of automatic clamping;
7, the detection of finished products and semi-finished products need a personalized fixture;
8, metal wire, steel wire and Other metal test, need to test the tensile tester fixture emery;
9, the large amount of deformation of the material required in a special fixture;
10, high temperature test fixture requires high temperature deformation fixture.

Fourth, Rally machine price
1, can not just look at the price;
2. It is necessary to combine the above aspects to determine the quality of the pulling machine.
3, need to consider the cost of follow-up use;
4, need to consider the stability of the quality;
5, need to consider whether the product is suitable for the use of its own products.

Fifth, Rally instrument brand
1, mainly to consider whether the tensile machine is a regular manufacturer;
2, whether the regular manufacturers pass the quality inspection honor production;
3, whether there is a certain degree of market visibility;
4, whether there is quality assurance;
5, whether there is after-sales service guarantee;
6, Dongguan Haida equipment promises free maintenance of all products for life!

Six, Rally instrument success stories
1. The market is an effective way to test products;
2. How many peers are using a pulling machine to show that the matching between the instrument and the industry is better;
3. The more successful cases, the instrument operation, stability, accuracy and other aspects are suitable and meet the needs of the industry;

Seventh, scientific research strength
1, Dongguan Haida instrument and a number of scientific research institutions to cooperate in research and development of the latest detection equipment;
2, has a number of national patent technology certificate;
3, have their own product laboratory.

In the purchase of rally instrument, we must know how to distinguish the quality of rally instrument, Haida instrument teach you how to distinguish between the quality of rally instrument!
