Coulomb Meter MODEL NK-1001/1002

The coulomb meter is a probe-type device that measures the size of the static charges that may cause electrostatic damage in the manufacturing, inspection, and assembly processes for electronic devices.

Many of the ESD phenomena that cause failures of electronic devices can be explained by the charged device model (CDM). In this model, the device itself is charged and, when an external electrode is grounded, a high peak current flows instantly. The quantity of static discharge, the integral of the current, can be measured with high accuracy by the coulomb meter.

- You can easily measure the quantity of static discharge just by bringing the coulomb meter into contact with the object to be measured (conductor).
- The quantity of static discharge due to induction charging can be measured for electronic devices and printed wiring boards surrounded by charged insulators.
- This measurement method checks on the actual electrostatic destruction phenomenon (CDM).
- The use of this contact method ensures very few measurement errors between different measurers.
- You can switch between two modes: peak hold and continuous measurement.
- A conductive probe tip, optionally available, allows you to safely measure sensitive products.
- An AC adapter, optionally available, comes in handy when you use this coulomb meter for evaluation, tests, etc. for extended periods.
- Using the optional ZHO-200PN, you can convert a device capacitance.
- Using the optional KQ-1400, this model can be used to measure a static charge. (Faraday cage method)
