Applications and Principle
ESD (electrostatic discharge) is a serious issue faced by the electronics industry. Modern microelectronic products are easily damaged by electrostatic discharge. Additionally, other industries are also significantly affected by static electricity, such as telecommunications, plastics, and explosive materials.
Electrostatic issues can lead to increased costs in time and finances, and also impact human health.
Static voltages as low as 100V can damage electrostatic sensitive components.
Static voltages exceeding 10,000V can harm the human body, clothing, materials, and equipment.
Static voltages above 3,000V can generate electrostatic sparks, and in hazardous areas, static electricity can even cause fires.
To find effective and reasonable solutions, it is first necessary to understand the causes of static electricity, its magnitude, and polarity. The Kleinwachter electrostatic field meter is perfectly suited for this purpose.
The EFM 115 is an easy-to-use electrostatic field monitor. Compact in size, it connects directly to a computer for operation and can be paired with the MK11 probe to monitor electrostatic voltage.
Software selects detection distance:
Pre-select the detection distance based on the required range; the software automatically converts field strength to voltage based on the distance.
