In electrostatic discharge (ESD) controlled environments, measuring surface resistance is a crucial step in assessing a material's antistatic properties. However, in practice, measurement results are often inaccurate if the measurement conditions or equipment do not meet technical requirements. These errors can lead to misjudging whether a material meets or does not meet ESD standards.

The Hipot test is a dielectric test used to assess the insulation capacity of equipment. When the test voltage is maintained for a sufficient duration and at a level higher than normal operating conditions, the voltage withstand capability of the ignition system becomes more apparent. This directly affects the safety of the equipment during operation.

Heating resistors play a crucial role in heating devices used in both domestic and industrial settings. When this component malfunctions, it's essential to inspect it promptly to identify the cause and address the issue in a timely manner.

Decibels (dB) are a unit used to express the loudness of sound, reflecting the sound intensity in various environments such as music, production, or daily life. Understanding how dB works helps you understand the noise levels you are exposed to, allowing you to protect your ears and adjust the volume accordingly.

Testing the insulation resistance is the first important step to evaluate the insulation condition of the device. From there, we can also monitor the change of leakage current over time. So what is the required insulation resistance value? This is a common question of many technicians, and the following article will help you understand better.

Are you searching for a budget handheld oscilloscope for electronics repair or personal projects? These low-cost devices often promise quick signal measurement without breaking the bank. But is a budget handheld oscilloscope truly reliable, or is it just a deceptive gimmick?

In the context of increasingly complex supply chains, inventory management has become a priority for every business. Handheld inventory devices appear as a tool to help change the way businesses control goods, from manual recording to a more automated, faster and more accurate process.

SF6 density measurement is an important step to evaluate the insulation capacity of high-voltage GIS cabinets. When the gas density does not reach the standard, the density relay may give an incorrect signal or malfunction in the equipment operation. Wuhan HTMD-H supports fast and accurate measurement, visual data display, result storage and report printing on-site or in the laboratory. The clear LCD screen, mouse operation and micro printer make SF6 relay testing easier.

Most first-year students when starting to get acquainted with electronic practice must use a multimeter. This is the first basic device to measure voltage, resistance, check circuit continuity and test components. To choose the right one from the beginning to avoid wasting time getting used to it again and ensure stable measurement results in labs, this article will help you.
