Clamp Meters
GAO’s electrical clamp meters are a type of electrical test instrument used to measure electrical current without the need to disconnect the circuit or make physical contact with the conductors. Our clamp meters work by using a magnetic clamp that can be opened and closed around the conductor, which induces a magnetic field in the clamp. This field is then converted into a measurable electrical signal, which is used to determine the current flowing through the conductor. They are particularly useful in situations where the current cannot be easily measured using other types of test instruments, such as when the circuit is live or the conductors are difficult to access.
GAO’s electrical clamp meters are composed of clamp, current transformer, measurement circuitry, display, function selection and range switches, power source, and input jacks.
The alternative names of a clamp meter include current clamp, amp clamp, ammeter clamp, current probe, tong tester, current sensor, AC/DC clamp meter, current meter, clamp-on ammeter, current tong, clamp-on current meter, clamp-on meter, jaw clamp meter, clamp-on amp meter, AC/DC current clamp meter, ampere clamp meter, non-contact ammeter, hall effect clamp meter and magnetic current meter.

GAO Tek’s electrical clamp meters have the following functions:Current Measurement: The primary function of our clamp meter is to measure electrical current. It can measure both AC and DC current by clamping around a conductor and using the built-in current transformer to sense the magnetic field generated by the current.
Voltage Measurement: GAO Tek’s clamp meters also provide voltage measurement capabilities. They can measure AC and DC voltages by using test leads or probes connected to the meter's input jacks. This allows users to measure voltage in circuits and electrical systems.
Resistance Measurement: Some of our electrical clamp meters have the ability to measure resistance, which is useful for checking the continuity of wires and components or for troubleshooting electrical connections.
Data Logging: Our electrical clamp meters come equipped with data logging capabilities. They can store measurements over time, allowing users to analyze trends and diagnose intermittent issues.
True RMS Measurement: True RMS (Root Mean Square) measurement capability is a valuable feature in GAO’s electrical clamp meters. It accurately measures the effective value of complex waveforms, including non-sinusoidal signals, which is crucial for obtaining accurate readings in various electrical systems.
