The ETS Model 230 NanoCoulomb Meter is a tool for measuring the electrostatic charge of a material. It is typically used in combination with Faraday Cups or a metal probe for taking charge measurements of a material.

The ETS Model 230 NanoCoulombmeter can directly measure electrostatic charge on conductive, dissipative, or insulative objects. The NanoCoulombmeter is ideal for testing items, such as ESD packaging, populated PC boards, electronic  devices.  The Model 230 can be utilized in accordance with industry standards and test methods that require charge measurements, including ANSI/ESD S541 and SEMI E78.
