UNI-T UT207A 1000A AC/DC Digital Clamp Meter – Heavy-Duty True RMS Current Tester with Inrush Current & Frequency Measurement

Overview 

The UNI-T UT207A is a heavy-duty, professional-grade 1000A AC/DC digital clamp meter engineered for industrial electricians, plant maintenance technicians, and high-power electrical contractors. Built to handle massive electrical loads without breaking physical circuit continuity, the UT207A combines high-current clamping with a full-featured digital multimeter suite. Featuring True RMS accuracy, inrush current measurement for motor startups, and a wide jaw capacity, it provides safe, reliable diagnostics for heavy machinery, solar installations, and commercial distribution panels on Hall Road and beyond.

Key Features 

• Massive 1000A AC/DC Capacity: Accurately measures high-current electrical lines up to 1000 Amps AC and DC using the wide-opening jaw clamp.

• True RMS Accuracy: Delivers precise voltage and current measurements on distorted waveforms, variable-frequency drives, and non-linear industrial loads.

• Inrush Current Measurement: Captures sudden surge currents during electric motor startups and compressor kick-ins to evaluate motor health.

• Full Multimeter Testing Suite: Beyond clamping, it measures AC/DC voltage up to 1000V, resistance, capacitance, frequency, diode tests, and continuity buzzers.

• Large Backlit LCD Screen: High-contrast digital display paired with a bright backlight for effortless reading inside dark electrical panels and switchgear rooms.

• Data Hold & Max/Min Modes: Easily freeze readings on screen or track peak fluctuating values during active load testing.

• CAT IV 600V / CAT III 1000V Safety: Rigorously insulated to meet strict industrial electrical safety standards, protecting technicians during high-energy testing.
