New intrinsically safe Fluke DMM delivers extreme ruggedness

16 June 2012

Fluke, the global leader in portable electronic test and measurement technology, has introduced the 28II Ex Digital Multimeter, a new rugged, intrinsically safe digital multimeter (DMM) that allows measurements both inside and outside of hazardous zones.

The Fluke 28II Ex DMM features a high-resolution 20,000 count display and true-rms AC voltage and current readings, for accurate measurement on non-linear signals. It measures up to 1000V and 10A AC and DC and its low pass filter ensures accurate voltage and frequency measurements on variable speed motor drives. The built-in thermometer function measures temperature from -200°C to +1090 °C, reducing the number of tools that need to be carried.

The Fluke 28II Ex DMM is:
*Intrinsically Safe: It meets global IS regulations, including ATEX, IEC Ex, ETL and GOST.
*Intrinsically rugged for use in the toughest environments: It is drop-proof up to three metres, with a totally sealed, IP 67 rated case for complete protection against dust and water. It can withstand hazardous 8,000V spikes caused by load switching or faults on industrial circuits.
*Intrinsically accurate and reliable: It provides all the test and troubleshooting power necessary for accurate measurements inside or outside potentially explosive areas.  This eliminates the need to carry multiple meters for different areas, and removes the safety problems associated with crossing through an intrinsically safe-required zone with a non-IS instrument. 

Backlit keypad buttons, large display digits and a two-level bright white background for visibility make it easy to use even when wearing full personal protective equipment. The battery lasts up to 800 hours and the separate battery compartment makes it easy to change batteries or fuses on the job without jeopardising the meter’s IS or IP ratings or sending the unit for servicing.

The Fluke 28II Ex comes complete with Fluke TL175 test leads, AC72 alligator clips, red holster, 9V battery (installed) and manuals. An optional magnetic hanger is available for easy, hands-free setup and viewing.
