The Fluke 28 II EX Intrinsically Safe True RMS Multimeter is an intrinsically safe digital multimeter (DMM) you can use in IIC (gas), in Zone 1 and 2 and IIIC (dust), Zone 21 and 22. 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.
Tested for drops of up to 3 meters (10 feet), waterproof and dustproof (IEC60529, IP67), this Fluke 28 II EX Intrinsically Safe True RMS Multimeter survives the roughest treatment in the harshest environments.
Like all Fluke DMMs, the 28II Ex delivers the accuracy and measurement performance you depend upon to succeed in your work, day after day.
