Fluke 28II Ex

Intrinsically Safe True-rms

Digital Multimeter

Intrinsically safe

The new 28II Ex certification allows you to

carry the most trusted name in DMM’s

into most Ex rated areas.

Intrinsically rugged

Tested for drops of up to 3 meters (10 feet),

waterproof and dustproof (IEC60529, IP67),

this completely sealed and extremely rugged

DMM survives the roughest treatment in the

harshest environments.

Intrinsically reliable

Like all Fluke DMMs, the 28II Ex delivers the

accuracy and measurement performance you

depend upon to succeed in your work, day

after day.

Intrinsically Safe. Intrinsically Fluke.

The 28II Ex: the most rugged intrinsically

safe digital multimeter in the world.

Now there’s one intrinsically safe digital

multimeter you can use in Class 1, Div. 1 -

Zone 1 and 2 (gas) Class 2, Div. 1 or Class

III - Zone 21 (dust) areas. Whether you work

in petroleum, chemical, or pharmaceutical

environments, all the test and

troubleshooting power you need is packed

into the most rugged intrinsically safe

(IS) DMM Fluke has ever built. The Fluke

28II Ex is also water-proof, dust-proof

and drop-proof. You’ll be equipped to

handle any situation, inside and outside of

hazardous zones, without compromising

compliance or measurement performance.
