Portable electronic test
and measurement
technology specialist,
Fluke, has introduced a new
rugged, intrinsically-safe
digital multimeter (DMM)
that allows measurements
both inside and outside of
hazardous zones, without
compromising measurement
performance. The Fluke 28II
Ex Digital Multimeter meets
intrinsic safety (IS) standards
worldwide for safe use inside
potentially explosive
environments, making it ideal for use
in petroleum, chemical and
pharmaceutical facilities.

The Fluke 28II Ex DMM features
a high-resolution 20,000 count
display and true-rms AC voltage and
current readings, for accurate
measurement on non-linear signals.

It measures up to 1000V and 10A
AC and DC and its low pass filter
ensures accurate voltage and
frequency measure ments on variable
speed motor drives. The built-in
thermometer function
measures temperature from –
200°C to +1090°C, reducing
the number of tools that
need to be carried.

Meeting global IS
regulations, including
ATEX, IEC Ex, ETL and
GOST, the Fluke 28II Ex
DMM is drop-proof up to
three metres, with a totally
sealed, IP 67 rated case for
complete protection against
dust and water. It can
withstand hazardous 8000V
spikes caused by load switching or
faults on industrial circuits.
