Color measurement principle: Color is a psychophysical quantity. People’s perception of color is realized by the light signal reflected or transmitted from the object received by the human eye. Color property is a three variable function, which can be described by the three elements of color: lightness, hue, and color saturation. The color of the light source is determined by the spectral di...
IPX1-7 waterproof test chamber can simulate the environment where electronic components or electronic products may be subjected to water spraying or splashing under the environment of natural rain to conduct waterproof test on products. The purpose is to test whether the product has waterproof character and meets waterproof requirements. What does the IPX1-7 tester mean? In fact, the font has ...
Products that have been painted, electroplated, covered with an inorganic or organic layer, handled an anode, treated with anti-rust oil, etc., may be put through their paces in a salt spray chamber to see how well they hold up to the elements. The salt spray test system (YWX/Q-010) is wall-mounted, so it may be installed anywhere and not interfere with testing. Since it uses an imported quartz no...
Definition of CIE 1931 chromaticity coordinates： Chromaticity coordinate The colors in the figure include the colors that nature can get. This is a two-dimensional planar space diagram, a plane composed of an x-y right-angle scale. It was designed to accommodate people’s habit of discussing variable relationships in a planar coordinate system. In the process of designing the graph, many ma...
Waterproof test chamber, also known as ip waterproof testing equipment, waterproof testing device, rain test box, etc., is an experimental equipment under simulated rain environment. It has a wide range of applications. For example, it can be used for household appliances, diving equipment, lighting fixtures, outdoor products and other different products. 1. Understand the enterprise’s tes...
Ring wave test generator is designed according to the IEC (the International Electro technical Commission) standard IEC61000-4-12, EN61000-4-12, ANSI-C62-41 and GB/T17626.12. This instrument is used for the simulative electrical network, the power supply of the reactive load and the control line switch, as well as sensing the ring wave of the low voltage cables terminal equipment caused by th...
Color difference has always been one of the common problems of printing product quality. Whether it is the same batch of products or between different batches of products, the appearance of color difference will greatly reduce the quality of products. In the process of printing, it is often because the paper is not enough or it is directly replaced by the printing paper whose whiteness seems to be...
Everyone’s perception and interpretation of color are very subjective. Different reasons include personal preference, age, eye fatigue and other physiological factors. People’s perception of color, such as nearsightedness and farsightedness, is also different. So the testing instruments required for the measurement of various colors in various industries are also various. First, let...
The Temperature Humidity Chamber is the key instrument for testing the temperature and humidity natural environment. It is mainly to carry out high temperature, low temperature and environmental humidity detection, and evaluate the temperature and humidity resistance characteristics of commodities to ensure that everyone’s products can operate normally under all natural environmental standar...
