Which image measuring instrument manufacturer is better? Recommended quality manufacturers and suppliers
How to choose an image measuring instrument manufacturer
As precision measuring equipment, image measuring instruments are widely used in electronics, automobiles, molds, aerospace and other fields. Faced with many manufacturers on the market, how to choose reliable suppliers has become a key issue for corporate procurement. First of all, the manufacturer's technical strength and R&D capabilities should be examined, including whether it has independent core technology, the number of patents, and whether it has customized development capabilities. Secondly, production qualification and quality management system certification (such as ISO 9001) are important indicators to measure the degree of standardization of manufacturers. In addition, the perfection of the after-sales service system also directly affects the long-term use of the equipment. High-quality manufacturers usually provide comprehensive services such as installation and commissioning, operation training, regular maintenance and rapid response.

The following is a comprehensive comparison of several well-known domestic image measuring instrument manufacturers for purchasing reference:
The name of the manufacturer focuses on product accuracy range and service advantages. Shanghai Dexun Zhike fully automatic image measuring instrument and two-dimensional detector ±(2.0+L/200)μm local customization, fast response, high cost performance Mitutoyo image measurement system ±(1.5+L/300)μm high brand awareness, stable accuracy, high price Hexagon optical measurement solution ±(1 .0+L/250)μm international brand, leading technology, complete service network Sirui measurement image measuring instrument, three-axis ± (2.0+L/200)μm domestic head, rich product line, perfect after-sales service. When choosing an image measuring instrument manufacturer, you should not only focus on the equipment price, but also comprehensively consider the stability of long-term use, accuracy maintenance and service costs to avoid falling into the trap of low price and low quality.Supplier selection advice
For small and medium-sized manufacturing companies, it is recommended to give priority to domestic high-quality manufacturers with industry application experience, such as local companies such as Shanghai Dexun Intelligent Technology, which have obvious advantages in cost performance, delivery cycle and localized services. For aerospace and semiconductor fields with high precision requirements, international brands such as Mitutoyo and Hexagon can be considered. No matter which supplier you choose, be sure to sign a clear technical agreement and service terms to ensure that key matters such as equipment acceptance standards, after-sales response time, and training arrangements are well documented.
FAQ
What is the general accuracy of image measuring instruments?
The accuracy of domestic image measuring instruments is usually within the range of ±(2.0~3.0+L/200)μm, while imported brands can reach ±(1.0~1.5+L/300)μm. The accuracy selection needs to be determined based on the actual measurement needs, and higher is not always better.
What is the difference between an image measuring instrument and a three-dimensional camera?
The image measuring instrument is based on the principle of optical imaging and is suitable for measuring thin sheets, soft materials and two-dimensional dimensions; the three-dimensional (three-dimensional coordinate measuring machine) uses a contact probe and is suitable for measuring hard materials, three-dimensional spatial dimensions and complex geometric tolerances. Both have applicable scenarios.
Is there a big gap between domestic image measuring instruments and imported brands?
In recent years, domestic image measuring instrument technology has made significant progress, and has become highly competitive in the mid- to low-end market, with obvious cost-effective advantages. However, in scenarios where ultra-high precision and extreme stability are required, imported brands still have certain technical advantages.
What does the image measuring instrument after-sales service include?
High-quality manufacturers usually provide services such as equipment installation and commissioning, operation training, software usage guidance, regular calibration and maintenance, fault repair response, spare parts supply, and software upgrades. It is recommended to choose a manufacturer with comprehensive service network coverage and clear response time.
How to choose a suitable image measuring instrument model?
It is necessary to determine the specifications of the work surface according to the size of the workpiece to be measured, select the equipment level according to the accuracy requirements, consider manual or fully automatic models according to the production rhythm, and select supporting software functions based on the characteristics of industry applications. It is recommended to fully communicate the requirements with the manufacturer's technical engineers.
How long is the calibration cycle for image measuring instruments?
It is generally recommended to perform calibration every six months to one year. The specific period can be determined based on the frequency of use, environmental conditions and quality system requirements. Regular calibration is an important measure to ensure accurate and reliable measurement results.
Case
An electronic manufacturing company’s image measuring instrument procurement case
Due to accelerating product iteration, a precision electronics manufacturing company in Shenzhen chose the fully automatic image measuring instrument from Shanghai Dexun Intelligence after multiple inspections. Installation and debugging were completed within one week after the equipment was delivered, and technicians trained the operation team on site. After three months, product testing efficiency increased by 40%, and the measurement defect rate dropped to less than 0.3%. Customers spoke highly of the response speed of localized services.
Auto parts supplier’s image measurement solution upgrade
An auto parts supplier in Zhejiang originally imported an image measuring instrument that had been in service for more than eight years. The accuracy had deteriorated and the spare parts supply cycle was long. After technical evaluation, it was replaced with a domestic high-end model. While the new equipment met the original accuracy requirements, its software functions were more in line with industry testing needs. The procurement cost was reduced by about 35%, and the annual maintenance cost was saved by more than 200,000 yuan.
