What is a Coating Thickness Analyzer? A coating thickness analyzer, also known as a coating thickness gauge, electroplating layer tester, or anti-corrosion layer detector, is an instrument capable of non-destructively measuring the thickness of coatings on various substrates. It can measure non-magnetic coatings (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) on magnetic metal su...
Overview Ball Pressure Test (Resistance to Heat) is a critical experiment for evaluating the heat resistance performance of insulation materials, primarily used to support and protect energized components. The testing temperature varies depending on the material’s application, typically requiring materials supporting energized components to be tested at 125°C. Given that electrical accessor...
Analysis of Combustion Safety Performance of Automotive Interior Materials Importance and Current Status Combustion safety performance is a critical indicator for automotive interior materials. Typically, interior materials in vehicles are combustible, making stringent control over their combustion characteristics crucial. Currently, there are various standards governing the combustion characteris...
The Impact of Salt Spray on Electronic Products and Mitigation Measures Salt spray is widely present in marine, atmospheric, terrestrial, lake, and river environments, inevitably exposing electrical and electronic products to salt-laden atmospheres. The effects of salt spray environment, ranking just after temperature, vibration, humidity, and dust, significantly accelerate the electrochemical cor...
What is a RoHS Tester? A RoHS tester is a specialized device used to ensure compliance with the European Union’s RoHS (Restriction of Hazardous Substances) directive. This directive aims to limit the use of specific hazardous substances in electrical and electronic products. The primary function of a RoHS tester is to measure the levels of the following six hazardous substances in products: ...
Impedance analyzers are crucial testing devices used to assess the impedance characteristics of electronic components, circuits, and materials. With the rapid advancement of electronic technology, impedance analyzers are increasingly vital in fields such as circuit design, material science, and biomedical engineering. Working Principle of Impedance Analyzers: The principle of impedance analyzers i...
Principle of Battery Internal Resistance Tester: The battery internal resistance tester is designed to measure the internal impedance and voltage of batteries. Its principle involves applying a 1 kHz alternating current (AC) signal to the test object and measuring the AC voltage drop to obtain the internal resistance value. In comparison to the principle of resistance measurement using a multimete...
Working Principle of Withstand Voltage Tester: Withstand Voltage Testing is a crucial process for assessing the ability of various electrical devices, insulation materials, and structures to withstand voltage. During the test, high voltage is applied to the insulation material without compromising its performance. The basic principle of a withstand voltage tester involves applying a voltage higher...
A surge, also known as a transient voltage or spike, refers to the phenomenon of voltage exceeding the normal operating voltage for a brief moment. Essentially, a surge is a rapid voltage pulse that occurs within microseconds. Common causes of surges include the startup or shutdown of heavy equipment, short circuits, power switching, and the operation of large engines. Surges can potentially cause...
