Martindale Electric is the
portable PD700 Proving
Device, designed for the testing of
contact voltage detectors up to 700V.

With around 1000 electrical
accidents at work reported to the
HSE each year and 25 resulting in
death, there are simple precautions
that need to be taken
when working with or
near electricity. The
most important
consideration must be to
ensure that all circuits
and equipment which are
being worked on are
proved to be dead. While
an obvious way to do this is
to lock off a circuit and
ensure no live source exists
by means of a voltage
indicator, how do you know
your voltage indicator is
performing correctly?
A Proving Unit such as the PD700
from Martindale Electric offers a
solution. It can generate high
voltages to 700V but also lower
voltages down to 50V which
can still be potentially
dangerous. Suitable for use
with Drummond Test
Lamps, Digital Multimeters
and Low Impedance
Voltage Testers to ensure
they are working
correctly, the PD700 also
has an indicator which
illuminates when lamps
and voltage testers
draw high currents.

Lightweight and
compact, PD700 comes with
batteries and carry case.
