In industrial production, when testing electronic components, it is necessary to use a High and Low Temperature Thermal Shock Chamber for detection and testing. It is used for temperature cold and hot impact testing. The time for temperature conversion is short and the change is fast, so that the temperature impact of product testing can be achieved. Under ultra-high and ultra-low temperature cond...
I. Standard for Surge Generator of Electronic Devices The national standard for electro-equipment surge generator is GB/T17626.5 (equivalent to international standard IEC61000-4-5). Surge Generator SG61000 5 II. The standards for lightning surge generator mainly simulate various situations caused by indirect lightning strikes (1) When lightning strikes the external line, a large amount of current...

The rapid temperature change test chamber can be said to be a rapid temperature change test chamber, which is used for inspecting the various performance indicators of products in aerospace, information electronics, instruments, materials, electrical and electronic products, and various electronic components under rapid temperature changes. Rapid temperature change test chamber: mainly used for e...
Spectrum analyzer, also known as signal analyzer, are devices that can graphically represent radio frequency signals and help us understand the properties and types of signals in order to deduce the modulation type and type of transmitter. In the military field, spectrum analyzers are widely used in electronic countermeasures and spectrum monitoring, and various radar signals, communication radio ...
Hot wire testing is a common method used to evaluate the flammability of materials. The Glow-wire Test Apparatus is the main tool used for this type of testing, and its structure and principle determine the accuracy and reliability of the test. This article will introduce the application of ignitability testing and the principle of Glow-wire Test Apparatus, in order to provide readers with a deepe...
The density and visibility of fog are related, and a haze meter can be used to understand this relationship. A haze meter is an instrument specifically designed to measure fog, which can effectively measure the density and visibility of the fog, allowing for a clearer understanding of the fog. It is composed of several smoothly surfaced rotating glass cups which can capture the fog and effectively...
Lightning and surges are common problems in power systems, especially in high-voltage power equipment. To protect equipment from the impact of lightning and surges, we need to use lightning surge generators. 5kv Surge Generators and 30kv surge generators are two commonly used devices. This article will focus on the performance differences between these two devices and analyze their applicable scen...
