Introduction: The outcomes of impulse voltage testing have a significant impact on the degree to which electrical components and insulation systems can maintain their authenticity and safety. Instruments that produce high-voltage pulses and are known as impulse voltage testers or surge generators are used for the purpose of simulating the effects of transient voltage occurrences. This article will...
Introduction: For successful signal analysis, troubleshooting, and optimization in the disciplines of radio frequency (RF) and wireless communications, knowledge of the frequency spectrum is required. Spectrum analyzers are crucial pieces of equipment for observing and evaluating radio frequency (RF) signals over a broad frequency range. This article will discuss the significance of spectrum analy...
The spectrophotometer is designed according to the principle of spectral type, while the ordinary colorimeter is designed according to the principle of tristimulus type. The colorimeter has high accuracy and increasing versatility. For this reason, it reduces the influence of sample surface, especially suitable for color quality monitoring and computer color matching) and SCE (a measurement method...
Introduction In the realm of electronics, there are a few different kinds of equipment that are used for the goal of measuring and analyzing electrical signals. One of these gadgets that stands out as a fundamental instrument that is used widely in electrical testing and troubleshooting is called an oscilloscope. In this article, you will learn about oscilloscopes, how they work, and the many vari...
Introduction The reliability and durability of the items that customers buy has a direct bearing on the level of satisfaction and commitment they feel toward a certain brand. Dust test chambers are specialized pieces of equipment used by manufacturers to verify whether or not a product is able to withstand challenging environmental conditions, such as exposure to dust and particles. These circumst...
The colorimeter is a color deviation testing instrument, which can automatically compare the color difference (color difference value) between the sample and the tested object（ Δ E）。 That is, to make a filter that simulates the spectral sensitivity equivalent to the color sensitivity of the human eye, and use it to measure the light of the sample plate. The key is to design the spectral sen...
Introduction The rapid development of technology has made electronic gadgets indispensable to modern living. We depend significantly on technology like smartphones, tablets, wearables, and smart home items to keep in contact with others and get things done. However, these many pieces of technical equipment all have a common foe: water. Electronic equipment is susceptible to water damage from a var...
Introduction In the field of optical measurements, the two most important tools for gathering and analyzing data pertaining to light are called radiometers and spectroradiometers respectively. In spite of the fact that they seem to be identical on the surface, each of these instruments was developed to perform a distinct function and has a unique set of characteristics. We are going to contrast an...
Color difference has always been one of the common problems in the quality of printed products. 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 the printing paper with the same whiteness is directly used to rep...
