Hall Effect Clamp Meters

Hall effect clamp meters primarily measure current, both AC and DC, passing through a conductor without interrupting the circuit. This is their main advantage over traditional multimeters that require breaking the circuit. Many models also come with features like data logging, true RMS measurement, and connectivity options.

Hall effect clamp meters can also be referred to as:

• AC/DC clamp meters
• Amp clamps - this name focuses on their primary function of measuring current, often abbreviated as amp.
• Tong testers -refers to the clamp-like jaws of the meter that "tong" around the conductor.
• Hall effect ammeters - a more technical term emphasising the type of sensor used.

Depending on the model, additional measurements may include:

• Voltage - measure AC and/or DC voltage by connecting test leads to dedicated input jacks.
• Resistance
• Frequency
• Leakage current - measure small leakage currents for safety testing.
• Power - calculate and display power based on measured current and voltage.

Overall hall effect clamp meters offer a safe, convenient, and versatile way to measure current in electrical systems. Their non-intrusive nature and wide range of capabilities make them an essential tool for anyone working with electricity.
