Key Features Hioki CM3289

– 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

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

– Measure even harmonic waveform components using the True RMS method

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

Quickly clamp wires in even more confined spaces!

A new sensor profile yields outstanding ease of use

True RMS model capable of accurately measuring even distorted waveforms

The waveform including harmonic components is calculated according to an RMS calculation formula and displayed. True RMS measurement yields accurate display values even when measuring a distorted waveform, for example from an inverter-equipped device or switching power supply.

A pocket clamp meter that can use flexible sensors

When connected to an optional flexible current sensor*, the CM3289 can be used to measure the current flowing in pairs of wires or in tangled or complexly routed wires around which it was not possible to apply a clamp-on sensor in the past.

Essential for electrical work: A thin card tester that fits in the pocket with all the capabilities of a clamp meter

The CM3289 delivers all the functionality of a clamp meter and card tester in the form factor of the latter. In addition to current measurement, this single instrument delivers voltage measurement, continuity check, and resistance measurement functionality.

Rugged, portable design that’s drop-resistant

Despite its thin, compact design, the CM3289 has an operating temperature range of -25°C to 65°C and can withstand being dropped from a height of 1 m onto concrete. It’s engineered for use in tough environments.
