Fluke 28 II Ex DMM digital multimeter for hazardous zones

Fluke Corporation has introduced the Fluke 28 II Ex DMM, a digital multimeter for measurements both inside and outside of hazardous zones. The device meets intrinsic safety (IS) standards worldwide (Qld pending) for safe use inside potentially explosive environments, making it suitable for use in petroleum, chemical and pharmaceutical facilities.

The product is rugged for use in tough environments. It is drop-proof up to 3 m with a totally sealed, IP67-rated case for complete protection against dust and water. It can withstand hazardous 8000 V spikes caused by load switching and faults on industrial circuits. It provides all the test and troubleshooting power necessary for accurate measurements inside and outside potentially explosive areas.

The device features a high-resolution 20,000-count display and true-rms AC voltage and current for accurate measurement on nonlinear signals. It measures up to 1000 V and 10 A 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 to 1090°C.

Backlit keypad buttons, large display digits and two-level bright white background for visibility make the product easy to use even when wearing full personal protective equipment. The battery lasts up to 800 h 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 product comes with TL175 test leads, AC72 alligator clips, red holster, 9 V battery (installed) and manuals. An optional magnetic hanger is available for hands-free set-up and viewing.
