|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.
Model No. (Order Code)
CAT IV 300 V (Current)
• The CM3289 is the successor to the popular 3280-20F with a redesigned thinner sensor to help you get into the tightest spaces.
|Video introducing the AC Clamp Meter CM3289|
The popular 3280-20F AC Clamp Meter has be redesigned with a thinner sensor to help you get into the tightest spaces.
|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.
|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.
