Clamp on Meters

  • Clamp On Meters

A clamp meter is an electrical test tool that combines a basic digital multi-meter with a current sensor.

Clamps measure current. Probes measure voltage. Having a hinged jaw integrated into an electrical meter allows technicians to clamp the jaws around a wire, cable or other conductor at any point in an electrical system, then measure current in that circuit without disconnecting/de-energizing it.
Beneath their plastic moldings, hard jaws consist of ferrite iron and are engineered to detect, concentrate and measure the magnetic field being generated by current as it flows through a conductor.

Clamp meters are preferred for measuring high levels of current. DMMs cannot measure 10 A of current for more than 30 seconds without risking damage to the meter.

Clamp meters offer a minimum current range of 0 A to 100 A. Many models have a range up to 600 A. Others go up to 999 A or 1400 A, and some plug-in clamp accessories such as Flex Clamps can measure as high as 25000 A.

Clamp meters are used on industrial equipment, industrial controls, residential/commercial/industrial electrical systems, and commercial/industrial HVAC.

  • Can Have Multiple Measurements (Amps, Volts, Ohms, Resistance, Temperature)
  • Wide Amp Ranges from 20Amps, to 25,000 amps.
  • Options for Hard Jaw Clamp or Flexible probe
  •  Accuracy Specification vary by Clamp
  • Can be using in LIVE mode, for more production efficiency.
