Electrical measuring instruments are devices used to determine the amount of electricity running on a system. The instruments are used in marine, construction, metrology, welding, oil, energy and mining.

There are at least seven types of electrical measuring instrument.
• Transducers are used in converting a signal in some type of energy to another. Acoustic, electrical, electromagnetic, chemical and mechanical are the kinds of energy transducers are able to work with. Types of transducer include active power transducer, frequency transducer, current transducer and electrical measuring transducer.
• Detecting and Indicating Instruments are used to determine the amount of energy supply circulating in a system. The unit of measurement used varies depending on the type of instrument used: watts for wattmeter, amperes for ammeter, volts for voltmeter and KVAR for varmeter.
• Measuring Bridges are originally made for laboratory usage. Currently, bridge circuits are applied to convert and filter during industry and manufacturing processes. Transformer Bridges, Wheatstone Bridges and Thomson Double Bridges are three of the most common kind of measuring bridges.
• Energy Meters are the most familiar types of electrical measuring instrument in the market. They are used to determine the amount of electricity consumed by a business or a house at a specific period of time. Common energy meters include volt-ampere-hour meter, watt-hour meter, static meter, electrodynamic meter and induction meter.
• Oscilloscopes are used as an electronic test instruments to observe the constantly changing signal voltages. Types of oscilloscope include measuring oscilloscope, storage oscilloscope and electrobeam oscilloscope.
• Signal Generators are also known as frequency generators and function generators. These devices are used to repair, troubleshoot, design and test technological gadget. These can also produce repeating and non-repeating electronic signals. The Frequency Modulated Signal Generator and Amplitude Modulated Signal Generator are two kinds of signal generators.
