It is suitable for electrical and electronic products and components research, production and QC department such as lighting equipment, low-voltage electrical appliances, household appliances, machine tool electrical appliances, motor, electric tools, electronic instruments, electrical instrumentation, information technology equipment, electrical equipment, electrical fittings and accessories.

Adopting the gournd-breaking optical imaging technology, data transmission and processing system,it is the world's fastest inner hole measurement instrument. Based on the theory of new model and original high resolution photographic, it can ensure the accuracy of measurement.

It is a set of precision efficient measuring instrument which integrates optical, mechanical and electrical.The image of the vertical projector can be either a positive of a negative image. Measuring is simple,intuitive and high efficiency. Under transmission light illumination, the contour measurement error is less than 0.08%.

Using the American original electric refrigerating high-performance Si-PIN detector, high resolution, wide detection range, it can detectthe RoHS, halogen, plating, alloy (including precious metals) and basic requirements of various kinds of conventional material analysis.

Excellent optical performance, diversified portfolio, it meets the modern biological, medical, scientific research and modern electronic industry on-line detection. The standard magnification is 7 x ~ 45 x; Equipped with auxiliary lens, the magnification can be 3.5 X to 180 X.

With the method of salt-spray corrosion to test the reliability of the measured samples. Salt spray test chamber can be divided into two kinds of neutral salt fog and acid salt fog. The difference is that the standard and test method is different. It is also known as "NSS" and "CASS test. It applys to spare parts, electronic components, metal materials of protective layer and industrial products.
