Current Measurement: Clamp meter’s primary function is to measure alternating current (AC) flowing through a conductor by clamping around the wire without breaking the circuit.

AC/DC Current Measurement: Our clamp meters can measure both AC and direct current (DC), providing flexibility for various electrical systems.

Voltage Measurement: GAO’s clamp meters ensure to measure voltage in both AC and DC circuits. However, voltage measurements are typically made by directly connecting the meter to the circuit.

Resistance Measurement: Our clamp meters have the capability to measure electrical resistance in circuits. This is useful for troubleshooting and identifying faults in the circuit.

Continuity Testing: GAO Tek’s clamp meters have a continuity test function to check if a circuit is complete. It typically produces an audible beep for a low-resistance circuit.

Frequency Measurement: Clamp meters with advanced features can measure the frequency of an AC signal, which is particularly useful in troubleshooting electronic circuits.

Temperature Measurement: Some of our clamp meters come with a temperature measurement feature, allowing users to measure the temperature of conductors or components.

Power Measurement: Clamp meters can calculate power (watts) in a circuit by combining current and voltage measurements.

Power Factor Measurement: Power factor is an important parameter in our electrical systems. Our advanced clamp meters can measure power factor, helping to assess the efficiency of the power distribution.

Peak Hold Function: Peak hold function in clamp meters allows to capture and display the highest current value observed during a measurement session. This is particularly useful for identifying transient spikes.

Data Logging: Clamp meters can log measurement data over time, providing a record of current fluctuations or other parameters.

Auto-Ranging: Auto-ranging capability in our clamp meters can simplify the measurement process by automatically selecting the appropriate range for the given measurement, making it user-friendly.

Jaw Size and Opening: Our clamp meters come in various sizes with different jaw openings to accommodate conductors of varying sizes.

Display and Backlight: Our clamp meters have a clear and easy-to-read display, along with a backlight feature, that enhances visibility in low-light conditions.

Safety Features: Clamp meters are designed with safety features such as overload protection and non-contact voltage detection to enhance user safety.
