Fluke Throws Down Its Toughest Tools: New Fluke 27 II and 28 II Digital Multimeters Shrug Off Dust and Water -- and Float

Designed for the Military and Tested to Withstand a 10-Foot Drop

EVERETT, WA.--(Marketwire - August 31, 2009) - Fluke Corporation, known for its durable handheld electronic test and measurement tools, has introduced its toughest tools yet: the Fluke 27 II and 28 II digital multimeters, designed to survive water, dust and rough handling that would kill other tools.

The new Fluke 27 II and 28 II digital multimeters (DMMs) define a new standard for operating in harsh conditions, 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 (5 °F to 131 °F). They will function in -40 °C temperatures for up to 20 minutes. They will operate in 95 percent humidity, and are designed and tested to withstand a 3 m (10 ft) drop.

The new Fluke 20 Series II Multimeters are built for industrial electricians, plant engineers and technicians who work in the toughest environments -- and anyone who wants the most durable DMM available. They are ideal for such job environments as:

--  Manufacturing plants, foundries
--  Food processing and bottling plants
--  Water and wastewater facilities
--  Marine service and repair
--  Mining, drilling and materials extraction
--  Outside testing in any weather

Federal Mine Safety and Health Administration (MSHA) approval is pending. When enclosed in their protective yellow holsters, both meters will float in fresh or salt water. Holsters are reversible to provide added protection for the display and controls when the meter is not in use. Both meters feature backlit keypad buttons, large display digits and two-level bright white display backlighting for easy visibility in low-lit areas.

Both meters will measure up to 1000 V ac and dc and up to 10 A (20 A for 30 seconds). They feature a 10,000 µF capacitance range and measure frequencies to 200 kHz. Both provide min/max and average readings to capture variations automatically and both provide both auto and manual ranging for maximum flexibility. They are powered by three AA batteries and provide an average battery life of 800 hours.

For safety, the Fluke 27 II and 28 II withstand hazardous 8,000 volt 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 600 V/CAT III 1000 V working environments.

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 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 30 kHz.
