Description

Yokogawa offers an inexpensive dedicated Clamp-on meter that allows you to measure from 20mAAC to 200AAC with a wide frequency response range. The CL320 is ideal for non-evasive electrical safety testing, measuring leakage current tests without powering down or disconnecting equipment – saving you time, without compromising on quality or safety.

The unique jaw design eliminates the influence of adjacent conductors or magnetic fields. This allows you to perform accurate and reliable tests in today’s crowded electrical environments. The tough and high-quality jaw design of the Fluke 360 leakage tester guarantees high stability for long-term repeatability and durability.
