Price Match Guarantee & Advice

The larger version of Extech's CA3010 clamp adaptor, the CA3018 has wider clamp opening of 18" (45.7cm).

Thanks to its flexible design, the CA3018 is suitable for testing in those spots where normal clamps would struggle. Just unscrew the cable, feed it around a conductor, lock it back into place and you'll be able to test AC current up to 3000A.

This adaptor is designed for use with most digital multimeters and clamp meters, provided they have a port for standard-sized banana plug inputs.
