What aspects can be compared in the selection of image measuring instruments

What aspects of the image measuring instrument can be compared in the selection. The market for image measuring instruments is extremely competitive, and users will also make various comparisons when choosing suppliers. Different manufacturers will provide users with different product recommendations. How to compare the prices of image measuring instruments to determine which brand is the best choice? This article will help you. 1. Check the measurement strokes, which refers to the larger range that each coordinate axis can detect. Different measurement strokes will directly affect the price of the image measuring instrument. When choosing an image measuring instrument, you must first understand the size of the workpiece to be measured, and the measurement stroke must Refer to the product size to be measured by the factory to determine the size of the machine stroke. If the measurement stroke of the measuring instrument is too small compared to the size of the product being measured, the workpiece cannot be measured. If it is too large, it will be too wasteful. 2. To check the measurement accuracy, you need to purchase the accuracy standard of the image measuring instrument according to the accuracy of the measurement product required by the factory. The factory standard and assembly standard of each instrument manufacturer and the accuracy of the actual instrument will be different. If the customer's product is measured If the accuracy is not high, you can choose general precision instruments. If the accuracy of the products to be tested is very high, you need to purchase high-precision measuring instruments. 3. Look at the control method of the instrument. In addition to manual control equipment, there are also automatic image measuring instruments controlled by motors on the market. The price difference between the two is very large. If the customer measures a large number of products, it is better to choose a fully automatic image measuring instrument to ensure measurement efficiency, and to choose self-developed software to obtain better compatibility and upgrade speed. 4. Look at the instrument lens. The commonly used lenses on manual and automatic machines are continuous zoom lens, fixed frame and fixed magnification lens. In addition to the above two lenses, automatic measuring instruments will also choose automatic zoom lens. The prices of imported lenses and domestic lenses are quite different. 5. During the warranty period, the cost-effectiveness of image measuring instruments must consider after-sales service. Cheap instruments may have low accuracy, poor stability, poor after-sales and short service life; imported measuring instruments may have relatively stable performance and longer service life. Service life, but the instrument upgrade is troublesome, the maintenance cost is high, and repair parts are not easy to find. Therefore, customers must find a regular manufacturer and guarantee after-sales equipment. Considering the price of after-sales service, domestic brands have advantages.

In addition to the above points, the control system, structure and materials, computer system, etc. will also affect the price of image measuring instruments. Users should analyze and compare according to measurement needs to choose high-quality and low-cost image measuring instruments.
