Fluke 27 II and 28 II Digital Multimeters - Flukes toughest tools yet

Fluke has introduced its toughest tools yet for industrial electricians, plant engineers and technicians who work in the toughest environments. The new Fluke 27 II and 28 II Digital Multimeters (DMMs) define a new standard for operating in harsh conditions that would destroy other tools, while delivering the features and accuracy to troubleshoot most electrical problems. Both meters are IP 67 rated for water and dust resistance and offer an extended operating temperature range of -15°C to +55°C. They will function in -40 °C temperatures for up to 20 minutes, will operate in 95% humidity, and are designed and tested to withstand a 3 metre drop.

The Fluke 27 II and 28 II DMMs measure up to 1000V AC and DC and up to 10A (20A for 30 seconds). They feature a 10,000 microF capacitance range and measure frequencies to 200kHz. Both provide min/max and average readings to capture variations automatically, and provide auto and manual ranging for maximum flexibility. Both meters feature backlit keypad buttons, large display digits and two-level bright white display backlighting for easy visibility in low-lit areas.

The Fluke 28 II provides additional functionality. It is a true-rms meter that features a high-resolution 20,000-count display mode and includes a built-in thermometer that enables users to take temperature readings easily without carrying a separate instrument. It captures peak, min/max readings and features a high-pass filter to ensure accurate voltage and frequency measurements on adjustable speed drives and other electrically noisy equipment. The Fluke 27 II is an average responding meter with extended AC voltage bandwidth to 30kHz.

For safety, the Fluke 27 II and 28 II DMMs withstand hazardous 8,000V spikes caused by load switching and faults on industrial circuits and comply with second edition IEC and ANSI electrical safety standards. They are safety rated for use in CAT IV 600V/CAT III 1000V working environments.
