Clamp Meters

A clamp meter is an electrical tester that combines a voltmeter with a clamp type current meter. Like the multimeter, the clamp meter has passed through the analog period and into the digital world of today. Created primarily as a single purpose test tool for electricians, today’s models have incorporated more measurement functions, more accuracy, and in some instruments, some very special measurement features. Today’s clamp meters have most of the basic functions of a Digital Multimeter (DMM), but with the added feature of a current transformer built into the product.
