Fluke 28 II EX Intrinsically Safe Digital Multimeter

The Fluke 28 II EX Intrinsically Safe Digital Multimeter is engineered for professionals working in hazardous environments, including petroleum, chemical, and pharmaceutical settings, where safety and reliability are paramount. This rugged, intrinsically safe DMM combines high-end testing and troubleshooting capabilities with a durable design that is drop-proof, waterproof, and dust-proof (IP67), ensuring dependable performance even under the most demanding conditions. Certified for use across multiple international safety standards—including IECEx, ATEX, NEC/CEC, PCEC, Simtars, and IEx—the Fluke 28 II EX allows technicians to perform critical measurements inside or outside ATEX zones without the need to carry multiple instruments or risk non-compliant equipment in hazardous areas.

Offering comprehensive measurement functions, this multimeter delivers precision with 4-1/2 digit resolution (20,000 counts) and True-RMS AC voltage and current readings, ensuring accuracy even on nonlinear signals. It supports measurements up to 1000 V and 10 A AC/DC (with Ex zone restrictions), and features specialized capabilities such as a low-pass filter for reliable readings on variable speed motor drives, frequency and duty cycle measurement for diagnosing VSDs and switching power supplies, and a 10,000 μF capacitance range for motor and component testing. Additional functions include resistance, continuity, diode, and conductance testing, as well as Min/Max-Average and Peak Capture for monitoring fluctuations and transients. The multimeter also offers relative mode to eliminate test lead interference, flexible auto and manual ranging, and Input Alert to protect users from incorrect lead connections.

Designed with usability and safety in mind, the Fluke 28 II EX features a large, bright, two-level backlit display and backlit keypad buttons for clear visibility even when wearing full PPE, while an optional magnetic hanger allows hands-free operation. Long battery life, typically 400 hours without backlight, ensures extended use in the field, and easy access to the battery compartment and fuses allows maintenance without compromising calibration. The Fluke 28 II EX is supplied with an Ex-holster, test leads, alligator clips, installed batteries, and a quick reference guide, making it a complete, ready-to-use solution for intrinsically safe testing and troubleshooting in hazardous industrial environments.
