HIOKI CM3291 | AC Clamp Meter | 2000 A, 46 mm jaw
Genuine Hioki CM3291 clamp meter from General Tech Services LLC, Saudi Arabia, with free Saudi Arabia shipping available.
Part No. CM3291
Product Overview
The Hioki CM3291 is a slim, pocket-size 2000 A AC True RMS clamp meter designed for rugged field measurement and electrical troubleshooting. Its clamp design allows current to be measured around a single conductor without opening the circuit, helping technicians work efficiently on electrical panels, motors and equipment.
The CM3291 measures 42 A, 420 A and 2000 A AC across a 40 Hz to 1 kHz frequency range. True RMS measurement provides reliable readings on AC loads where waveforms may be distorted, including applications involving variable-speed drives, LED lighting and switching power supplies.
In addition to AC current measurement, the CM3291 provides resistance measurement from 420 Ω to 42 MΩ and continuity testing, along with data hold and automatic power-saving functions. Its 46 mm jaw, with a jaw opening of approximately 65 W × 13 D mm, accommodates larger conductors while maintaining a compact form factor.
At approximately 16 mm thick and 103 g, the meter is designed for portable field use. It operates for approximately 70 hours from a CR2032 coin cell and is designed to withstand a 1 m drop. The operating temperature range is −25 to 65 °C.
For applications requiring higher current capacity or a larger conductor opening, the optional CT6280 flexible sensor can extend measurement capability to 4200 A on conductors up to 130 mm, subject to compatible instrument configuration.
The CM3291 has a CAT IV 300 V / CAT III 600 V safety rating. It does not support Bluetooth or the Z3210 wireless adapter.
