Description
M-240+ AC/DC Mini Digital Clamp Tester30mmφCT, ACA, DCA
The M-240+ AC/DC Mini Digital Clamp Tester is a compact current measurement instrument designed to measure both AC and DC currents across two selectable ranges of 20A and 200A. Its 30 mm CT opening and slim body make it suitable for measurements in confined or difficult-to-access areas.
The tester features a 3.5-digit LCD with a maximum display count of 1999 and a data-hold function for retaining readings when direct viewing is difficult. Measuring just 44 × 148 × 20 mm and weighing approximately 100 g, the M-240+ combines AC/DC current measurement with a compact, portable design.
