Introducing the New Power Clamp-on Meter
Models 405 & 605

The ONLY 1000V CAT IV Clamp-on Meter on the Market!

The AEMC® Power Clamp-on Meter Models 405 and 605 provide a new standard for safety and measurement capability not available in any other clamp-on meter sold today. With a safety rating of 1000V CAT IV, these meters are safe to operate at the source of the buildings electrical supply. In addition to the standard measurement of TRMS volts, TRMS amps, frequency, resistance, continuity and diode tests these meters offer several unparalleled features including:


  • Measures TRMS Voltage and Current:
    405 - 1000VAC/DC, 1000AAC/1500ADC
    605 - 1000VAC/DC, 2000AAC/3000ADC
  • True InRush®: Unlike other instruments which only measure InRush when the installation is first powered up, these clamp-on meters measure all types of InRush, even those due to load increases on an installation which is already up and running (this is an exclusive AEMC® feature). Both Peak and RMS InRush values are captured at a 1ms sample rate and 100ms duration windows.
  • Phase Rotation: Evaluated by simply selecting the function, then measuring the voltage on two phases in sequence. An internal algorithm then calculates the phase rotation and displays the results.
  • Power: These unique meters are capable of measuring power in the megawatt range down to 1W resolution. Real, Reactive, Apparent Power and PF are displayed.
  • Harmonics: Measures and displays Total Harmonic Distortion for V and A. Both THDr and THDf are displayed.

Add to this an IP54 environmental rating and you have a truly unique meter focused on user safety, as well as measurement performance.
