The Fluke 87V-Ex is the intrinsically safe version of the most popular meter in the world, the Fluke 87V. Intrinsically safe (I.S.) are protected methods employed in potentially explosive atmospheres. Certified I.S. tools are designed to prevent the release of sufficient energy to cause ignition of flammable material.

I.S. standards apply to all equipment that can create one or more of a range of defined potential explosion sources such as electrical sparks, static electricity and mechanical friction. I.S. tools are designed for industries such as petro-chemical, grain processing, oil platforms and refineries, pharmaceutical and pipelines as well as other hazardous environments.
