Flash meter in the measurement speed, accuracy, ease of operation and adaptability has significant advantages, but the range of limited, relatively narrow measurement function, high requirements for the test environment, as well as more difficult to maintain and higher prices and other shortcomings also limit its application in some aspects. When choosing to use flash tester, need to be based on specific needs and the actual situation for comprehensive consideration and evaluation.

Advantages

Measurement speed: flash tester can realize “second-class” measurement speed, compared with the traditional measurement tools, measurement efficiency is significantly improved; applicable to high-volume, rapid measurement needs, such as precision hardware accessories, 3C electronic precision parts.

High measurement accuracy: avoid the influence of Abbe error due to the increase of measurement stroke, high repeat measurement accuracy; Equipped with high-resolution camera and advanced image processing algorithm, it can realize micron-level measurement of the measured object size.

Easy to operate: no need for professional operation, the workpiece can be placed at random, a key to complete the batch measurement; support for non-contact triggered measurement, can be triggered by waving your hand in front of the camera, simple and fast.

Diversified functions: able to measure different features on the workpiece, and the number of dimensions that can be measured at one time is large; equipped with a variety of lighting modes, the projected profile of the part, surface profile, etc. can be clearly obtained.

Strong adaptability: large measuring field of view, able to meet the measurement needs of workpieces of different sizes; can be applied to a variety of industries, such as cell phone industry, automotive industry, precision parts industry, etc.

Disadvantages

Limited range: in order to ensure the measurement accuracy, flash tester range is generally small, usually does not exceed a certain limit (not more than 300mm * 200mm * 75mm); this limits the flash tester in some large-size workpiece measurement applications.

Measurement function is relatively narrow: flash tester is mainly applicable to the plane of the basic geometric dimensions of the measurement and evaluation of tolerances; for complex shapes or three-dimensional dimensional measurement, may need to rely on other measuring equipment or methods.

Higher requirements on the test environment: the test accuracy of the flash test instrument may be affected by the test environment, such as light, temperature, etc.; in the use of the flash test instrument for measurement, you need to ensure that the stability and suitability of the test environment.

Difficulty in maintenance: the structure of the flash meter is more complex, when encountering faults need to carry out professional maintenance; maintenance process on the operator's high requirements, requiring a certain degree of professional knowledge and experience.

Higher price: as an advanced measuring device, the price of the flash meter is usually higher; this may increase the enterprise's purchasing cost and cost of use.
