IPX7 Immersion tank Waterproof test Device indicates that the waterproof grade of the product is 7. When the product is immersed in water for a short time under standard pressure, it will not enter the interior even if it is immersed in water under specified conditions. It is described in detail in GB 4208. This grade belongs to a higher waterproof grade. It is generally placed in the environment ...
Lightning surge damage to electronic/power equipment has been a topic of concern around the world. In this regard, many electronics engineers have developed various lightning surge generator for protecting electronic/power equipment. Among them, DC (DC) and AC (AC) protection modules are commonly used, and the DC protectors are mainly applied in signal systems while the AC protectors are mainly us...
Introduction The automobile sector has a tremendous issue from corrosion, which reduces vehicle longevity, safety, and overall performance. Due to the wide range of environments to which automotive parts are subjected, comprehensive corrosion testing is essential before they can be relied upon. Corrosion resistance of automotive materials and coatings may be determined with the use of a salt spray...
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...
The needle flame test is the main test item to verify whether electronic products and materials are flame retardant. It simulates the small flame that may result from overheating in the fault or overload conditions of electronic products and components, and reproduces the actual situation, so as to evaluate the fire risk of the product through simulation technology. Combining the requirements of I...
Introduction In the realm of electrical engineering, surge generators play a crucial role in simulating controlled surges and transient occurrences. These units have a number of parts that work together to produce and send surges to the tested electrical systems. To fully grasp how surge generators work, one must be familiar with their components and the functions they serve. This article goes int...
What is a lightning surge simulator: Lightning surge simulator is a device that can generate high voltage and high current transient pulses, used to simulate lightning strikes and other sudden electromagnetic interference situations, in order to test and evaluate the tolerance and anti-interference ability of electronic equipment and power systems. Working principle of lightning surge simulator: ...
In recent years, the issue of Electromagnetic Interference (EMI) has gained more and more attention. There are two forms of EMI, namely conducted interference and radiated interference. Conducted interference refers to the signal from one electrical network being coupled (interfered) into another electrical network through conductive medium. Radiated interference refers to a signal in one system b...
The cosmetics industry is highly reliant on color measurement since customers put a significant amount of significance on the way a product seems to be colored. Prior to making a purchase, one of the primary considerations that buyers give their attention to is the color of the product. Portable spectrophotometers stand out in terms of their better simplicity of use and accuracy in comparison to m...
