Fluke 28 II Ex Intrinsically safe true RMS digital multimeter

• Intrinsically safe for hazardous areas
• Reliable
• Robust and sealed for extreme conditions

There is now an intrinsically safe digital multimeter (DMM), which you can use in areas IIC (gas) Zone 1 and 2, and IIIC (dust) Zone 21 and 22. If you work in the petrochemicals sector, chemical or pharmaceutical industry, you can find all necessary measurement and troubleshooting functions in the most robust intrinsically safe multimeter that Fluke has ever made. The Fluke 28 II Ex is protected against temporary immersion in water, dust-proof and shockproof in accordance with protection class IP 67. It is designed to help you manage any task, in hazardous and non-hazardous areas, without compromising on features or measuring performance.

A single tool provides you with all the functions for complete testing and troubleshooting, whether within or outside ATEX Zones 1, 2, 21 or 22. You no longer have to carry several measuring instruments for different areas or need to be concerned about entering a hazardous zone with a non ATEX-certified device.

• 4-1/2 digits for precise measurements
• True RMS of AC voltage and current for correct measurement results with non-linear signals
• Measures up to 1000 V and 10 A AC and DC (please note that lower values are measured in hazardous zones)
• Low-pass filter for precise voltage and frequency measurements of variable-speed drives (VSDs)
• Measurement of frequency up to 200 kHz and duty cycle in %, in order to take measurements and diagnoses of VSDs and switch-mode power supplies (SMPS)
• Resistance measurement, continuity test and diode test
• 10,000 µF capacitance range for components such as motor capacitors
• Conductivity measurements for high-impedance components or leakage tests
• Min/max/average and peak value detection for the automatic recording of transients and deviations
• Relative mode to remove the test lead interference with resistance measurements
• Auto and manual range selection for maximum flexibility
• Protection by an audible alarm and warning message "lead" (test lead) on the display, if test leads are connected to incorrect inputs
