The Fluke 27 II and 28 II digital multimeters (DMMs) can operate in harsh conditions while delivering features and accuracy to troubleshoot most electrical problems.

Both meters are IP67 rated for water and dust resistance and offer an extended operating temperature range of -15C to +55C.

They will function in -40C temperatures for up to 20 minutes, will operate in 95 per cent humidity and are designed and tested to withstand a 3m drop.

The Fluke 27 II and 28 II DMMs measure up to 1,000V 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 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 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 1,000V working environments.

The Fluke 27 II and 28 II DMMs are suitable for jobs in manufacturing plants, foundries, food processing and bottling plants, water and wastewater facilities, marine service and repair, mining, drilling and materials extraction, and outside testing in any weather.

When enclosed in their protective yellow holsters, both meters will float in fresh or salt water.

The holsters are reversible to provide added protection for the display and controls when the meter is not in use.

Fluke Calibration

Fluke Corporation was founded in 1948, specialising in electrical test and measurement products. Early in its history, Fluke recognised that the very best electrical metrology would be needed to support its products and undertook to develop this capability. From this activity, the calibration business was born. Over the years, many breakthrough calibration products were introduced, establishing Fluke as a leader in electrical metrology.

In 2000, Fluke acquired Wavetek Precision Measurement. In 2001, Fluke’s calibration business expanded into the temperature field with the acquisition of Hart Scientific and then into pressure and gas flow with the acquisition of DH Instruments (2007), followed by Ruska and Pressurements (2010).

The unified business’s unmatched breadth and depth in metrology puts Fluke Calibration in a unique position to deliver today’s and tomorrow’s calibrations solutions to customers who demand the very best, supported by an organisation they can count on for the long term.
