CM3289 – AC Clamp Meter

Overview

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.

CAT IV 300 V (Current)
CAT III 600 V (Current)
CAT III 300 V (Voltage)
CAT II 600 V (Voltage)

Key Features
