allsun 400A AC/DC Current Clamp Probe True RMS Multimeter CAT III 600V

Key features

• PRECISION AC/DC CLAMP METER W/ HALL EFFECT TECH Accurately measure AC/DC currents up to 400A (600A overload) using advanced Hall Effect sensor technology. Features True RMS conversion, dual-range sensitivity (40A: 10mV/A; 400A: 1mV/A), and ±2.5% accuracy—suitable for HVAC, automotive diagnostics, and industrial circuits.
• NON-CONTACT CURRENT TESTING & SAFETY33mm jaw opening safely measures conductors up to ∅28mm without circuit interruption. CAT III 600V rated with tactile barriers and double insulation. Includes polarity detection and CE certification for shock prevention.
• BATTERY & ZERO CALIBRATION Visual battery alert (Green/Red LED) warns at ≤7.5V. One-touch zero calibration eliminates DC drift errors. Auto-off function (dual OFF positions) extends 9V battery life during storage.
• PROVEN TO WORK WELL WITH OTHER 3RD PARTY MULTI-METERSSeamless integration with any multimeter via DC voltage output (0-400mV). Features dedicated range switch, AC/DC mode selection, and trigger-operated jaws. Auto-calculates current using Reading/Sensitivity formula.
• PORTABLE INDUSTRIAL-GRADE TESTERCompact handheld design for tight spaces. Withstands 0°C–40°C environments. Perfect for electrical troubleshooting, motor maintenance, factory QA, and energy audits. Includes wipeable casing for durability.
