An electrostatic fieldmeter, also called a static meter is a tool used in the static control industry. It is used for non-contact measurement of electrostatic charge on an object. It measures the force between the induced charges in a sensor and the charge present on the surface of an object.
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.

An electric charge near a metal object causes the mobile charges in the metal to separate. If the external charge is positive as shown, negative charges (blue) are attracted and move to the surface of the object facing the external charge, positive charges (red) are repelled and move to the surface of the object facing away.
Digital sensors are widely used in water and industrial processes. They measure parameters such as pH, redox potential, conductivity, dissolved oxygen, ammonium, nitrate, SAC, turbidity. A digital sensor system consists of the sensor itself, a cable, and a transmitter. The differences with analog sensor systems are: a) The sensor has an ...
Gold leaf electroscope showing electrostatic induction Using an electroscope to show electrostatic induction. When a charged resinous (-) rod touches the top ball terminal, electrons are conducted down through the post to the needle; so the post repels the needle, turning it counter-clockwise.

The electrostatic field inside a piece of metal is always zero. If it was not, the force of the field would cause more motion of charges and more charge separation, until the electric field became zero. Once C is well inside the container, almost all of the electric field lines from C strike the container surface. [11]
