Product overview: Fluke 28 II EX Intrinsically Safe Digital Multimeter

Fluke 28 II EX Digital Multimeter

All the measurement functions of our most popular industrial Digital Multimeters

Now there’s one intrinsically safe digital multimeter (DMM) you can use in IIC (gas), in Zone 1 and 2. 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 28 II Ex is also waterproof, 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.

One tool equips you with all the testing and troubleshooting power you need wherever you go––inside or outside ATEX zones 1or 2. No need to carry different meters for different areas, or worry about crossing through an Ex-required zone with a non-Ex rated instrument.
