The screen detector uses high-power telecentric optical path technology and screen-specific software processing capabilities, and uses a large field of view and a large screen to achieve rapid measurement of mesh-like workpieces. It can be used for calibration and verification tests in metrology institutes, scientific research institutions and factories Quality control of screen and acoustic mesh products.

· The screen can be screened according to the methods stipulated in the current national measurement calibration standard JJF1175-2007 "Test Screen Calibration Standard" and the national standard GB-T6003.1-2012 "Test Screen Technical Requirements and Inspection Part 1: Metal Wire Braided Wire Test Screen" Rapid detection of mesh size, automatically output mesh aperture (maximum, minimum, average, number of meshes tested), wire diameter, maximum diameter deviation, maximum wire diameter deviation, standard deviation, mesh hole size distribution, etc. Parameters, automatically generate test report or original measurement and certificate report;

· Quickly obtain the size data of tens of thousands of meshes, ensure the data sampling rate, automatically complete the statistical analysis of the test data, and generate original data records and certificates (or generate customized product test reports in real time), more accurately and quickly achieve Evaluation of the quality of the test screen;

· It can realize high-precision digital rapid measurement of the sample size of the test grid and the like with a planar grid feature. Multi-area and large-area sampling tests can be performed on the entire screen surface according to four different sampling methods: single-turn, multi-turn uniform, random, and custom. · High precision, high efficiency, <1 second / piece;

· The magnification of the measurement system is adjustable, which can meet the measurement needs of all test screens and mesh products within the aperture range of 20μm ~ 3mm;

· This equipment can also be used to measure the mesh number, wire diameter, hole width, opening rate, thickness and other parameters of the acoustic net. Based on the multi-purpose software processing function, it can also be used as an ordinary image measuring instrument to measure various parts.
