With the newest additions to our family
of clamp meters, we provide a range of
state-of-the-art features that meet even
the most demanding job requirements.
Faced with crowded cabinets? Our
365 model offers a small, detachable jaw,
while four other models can use our flexible
current probe, called the iFlex, to squeeze
between tightly packed wires or around
large conductors.
Need an extra hand? The 381 includes
a detachable display that easily allows
for remote measurements.
All six of our new clamp meters have
improved base features such as a large,
backlit display, true-rms standard and
a durably constructed body. Additionally,
five of our models are CAT IV rated.
In short, innovation meets safety in
this truly flexible family of clamp meters,
all designed with you in mind. We are
committed to making your life easier.
