ATEX True-rms Digital Multimeter / ZONE 1/21

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.
