Fluke 28II Ex

Intrinsically Safe True-rms

Digital Multimeter

Intrinsically safe

The new 28II Ex certification allows you to

can 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 (DMM) you can use in IIC (gas)

Zone 1 and 2 and IIIC (dust) Zone 21 and

22 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.
