Multimeters can measure several electrical properties, including voltage, current, and resistance. They typically have a digital or analog display that shows the measurement values. Multimeters come in handheld, benchtop, and specialized versions, and they are essential for diagnosing electrical problems in a wide range of applications.

Clamp meters use a magnetic sensor that can detect the magnetic field generated by the current flowing through the wire, and they can measure both AC and DC currents. They are particularly useful for measuring currents in high-power applications such as electrical panels, motors, and generators.

Insulation testers are electrical instruments used to measure the insulation resistance of electrical devices and systems. They apply a high voltage to the insulation and measure the resulting current flow. This test can help identify problems with insulation breakdown, contamination, or deterioration. Insulation testers are used in applications such as electrical motors, transformers, and cables.

Power analyzers are specialized electrical instruments used to measure the electrical properties of power systems. They can measure voltage, current, power, and energy in both AC and DC systems. Power analyzers are used in applications such as power generation, distribution, and consumption to optimize power usage and identify problems with power quality.

Battery testers are electrical instruments used to measure the performance of batteries. They can measure the voltage, current, and capacity of batteries to ensure that they are operating correctly. Battery testers are used in a range of applications, including automotive, industrial, and consumer electronics.

Precision DC voltmeters are highly accurate electrical instruments used to measure DC voltage with high precision. They typically have a resolution of several decimal places and are used in applications that require highly precise voltage measurements, such as research, development, and calibration.

LCR and impedance meters are specialized electrical instruments used to measure the electrical properties of capacitors, inductors, and resistors. They can measure parameters such as capacitance, inductance, resistance, impedance, and phase angle. LCR and impedance meters are used in applications such as research, development, and production of electronic devices and components.
