With the development of electronic technology, household electrical products are becoming increasingly popular and electronic, and the increasingly developed radio, television, post and telecommunications and computer networks, and the electromagnetic environment is becoming increasingly complicated and deteriorating, making the electromagnetic compatibility of electronics (EMC electromagnetic int...
The IPX9K High Temperature Pressure Jet Waterproof Test Chamber is one of the purposes of testing whether the product has waterproof performance in various environments where electrical components and electronic products may be exposed to rainwater or splashing, using a manually manufactured system to simulate natural rainwater environments, In addition, it can also detect whether the product mee...
Whiteness is the attribute of high reflectivity and low saturation (purity) of color. White is a color group, which is in the narrow range of 470~570 nm in the main wave length. Generally, its brightness y>70, and its excitation purity Pe<0.1. Although white is not a single color (monochrome), most observers can still arrange the order according to the different spectral reflectance, excitat...
Properties of three colors: The quantitative representation of color perception difference is based on the difference of three color attributes: lightness, hue and chroma. The lightness difference represents the difference in depth, the hue difference represents the difference in hue (i.e., red or blue), and the chromaticity difference represents the difference in brightness. Color difference asse...
1. Cleaning and maintenance inside and outside the Temperature Humidity Chamber ①. Before the high and low temperature test, the internal impurities must be removed. ②. The power distribution room shall be cleaned at least once a year, and the indoor dust can be removed by vacuum cleaner after each cleaning. ③. The surface of the chamber shall be cleaned and wiped more than once a year. 2....
Introduction of Integrating Sphere: The integrating sphere is a hollow sphere. The shell is generally made of metal. The inside of the shell is coated with a mansion. There are two or several light holes on the wall. The working principle of the integrating sphere is shown below. The light transmitted by the light source becomes parallel to the inside of the integrating sphere through the concentr...
The WS Series Temperature Rise Tester fully complies with the requirements of IEC 60884-1 Clause 19 (GB/T 2099.1 Clause 19); IEC 60669-1 Clause 17 (GB 16915.1 Clasue 17); and IEC 60998-1 Clause 15 (GB/T 13140.1 Clause 15). It uses voltage and current to simulate the tested object (e.g., household appliance plugs, sockets, and connectors) under normal operating conditions to measure its temperature...
What is the waterproof jet test device? The waterproof jet test device can also be called IPX56 test device, hand-held water sprayer, flushing test machine, etc. It is an open waterproof test equipment belonging to IPX56, and it carries out a level 5 or 6 waterproof test on the product. It is mainly used for electronic and electrical products, lamps, electric cabinets, electrical components, auto...
The High and Low Temperature Humidity Chamber is a kind of testing mechanical instrument used to test the extent of endurance of material structure and composite materials under the continuous environment of extremely low temperature or extremely high temperature, and to test the chemical change damage caused by thermal expansion and contraction. 1. Cooling function: The compressor of the High and...
