Hioki clamp meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CM3289 is a True RMS rectifying 1000A AC clamp meter that features a broad operating temperature range of -25° C to 65° C, thin and compact clamp core and optional flexible current sensor that you can attach to let you get into the tightest spots.

Features:

• The CM3289 is the successor to the popular 3280-20F with a redesigned thinner sensor to help
you get into the tightest spaces.

• New redesigned sensor for even easier clamping (CM3289)

• Expanded -25 °C to 65 °C operating temperature range

• Model CM3289: Measure even harmonic waveform components using the True RMS method

• Model 3280-10F: Measure the fundamental waveform component using the average rectified
method

• Connect the CT6280 flexible sensor to measure up to 4199 A in thick or paired wires
