AC Current Probe
Model SR752

The Model SR752 is designed for use
in industrial and utility environments.
The unique ergonomic design allows it
to easily clamp onto cables or small
bus bars. It is built to the highest safety
and performance standards including
the CE Mark and is UL approved for
Canada and United States.

Excellent transformation and low
phase shift, plus a broad frequency
response, permit accurate measure­ments of current for power and power
quality measurements. The high
quality magnetic cores and uniform
windings provide sensitivity for very
low level current measurements, as
well as measurements up to 1200A

AC.

The Model SR752 provides an
accurate voltage of 1mV/A. This
voltage output enables instruments
without current ranges to measure,
display and log currents through an
AC voltage range or measure very
low AC.
