Hioki Launches AC Clamp Meter CM4141 and CM4142

Hioki announced the launch of the AC Clamp Meter CM4141/CM4142 (rated for use with currents of up to 2000A), a pair of clamp AC current meters featuring a new jaw shape designed to make the instruments easier to clamp around wires.

Last year, Hioki launched the AC Clamp Meter CM3289 (rated for use with currents of up to 1000 A) in March, followed by the AC/DC Clamp Meter CM4375/CM4376 (also rated for use with currents of up to 1000 A) in October. All three instruments are designed to be easier to fit around wires being measured.  The newly launched CM4141/CM4142 fill out the company’s line of clamp meters while boosting work efficiency and resolving user dissatisfaction stemming from the difficulty of applying conventional clamp meters to wires in an increasing number of settings.

Hioki reduced the width of the jaws near the opening to 11 mm to make the instrument easier to clamp around wires (jaw thickness at the same position ranged from 15 mm to 22 mm in previous products). In addition, whereas the CM3289, which was launched last year with a design that is easier to clamp, can measure cables with a diameter of about 33 mm, the CM4141 and CM4142 can measure cables with a diameter of up to 55 mm, providing the ability to measure even thick cables without needing to connect a flexible sensor (more info).
