描述

The MA120-NIST is a 200A AC mini clamp meter with built-in non-contact voltage detector and flashlight, designed to increase user safety by detecting dangerous voltages before measurement. It measures AC current up to 200A with 100mA resolution and 3% basic accuracy, featuring a 0.7" (18mm) jaw opening suitable for 300MCM cable sizes. The meter includes a 2000-count LCD display, non-contact AC voltage detection at 120/240VAC (50/60Hz) via the clamp tip, frequency measurement up to 1kHz with 0.01Hz resolution, and a built-in white LED flashlight. Additional features include autoranging, auto power-off, data hold, overload protection, and operates on two AAA batteries. This NIST-traceable calibration version is ideal for applications requiring certified measurement accuracy in electrical maintenance, troubleshooting, and safety-critical environments.
