What is another word for electrometer?
Pronunciation: [ɪlˌɛktɹə͡ʊmˈiːtə] (IPA) 
An electrometer is a scientific instrument used to measure electrical charge or potential. There are several synonymous terms for an electrometer, including electrostatic voltmeter, electrostatic potentiometer, and Coulomb meter. An electrostatic voltmeter is an electrometer that measures the voltage between two points through the electrostatic force. An electrostatic potentiometer is another term used for an electrometer that measures potentials by using a balance of forces between gravity and electrostatic forces. The term Coulomb meter is often interchangeable with electrometer and refers to a device that measures electric charge in Coulombs. While these terms may vary, they all refer to instruments used to measure electrical charge or potential in various scientific applications.
