HIOKI CM3289 True RMS AC Clamp Meter 1000 A | Slim Jaw | WA

The HIOKI CM3289 AC clamp meter is a True RMS instrument optimised for daily electrical measurement work in panel environments, load surveys, and maintenance inspections. True RMS measurement is essential for accurate current readings where variable speed drives, LED lighting, UPS systems, and other non-linear loads distort the current waveform — a common situation in commercial and industrial buildings.

The 40 mm slim jaw fits comfortably around most cable sizes found in LV distribution panels, and the hold function freezes the display for easy reading when the meter is in a position where the display is difficult to see directly. At approximately 170 g, the CM3289 is one of the lightest instruments in its class, reducing fatigue during extended electrical survey and maintenance work.
