Fluke Introduces Advanced Clamp Meters

September 29, 2010

Engineered for the most demanding conditions, the new family of clamp meters features increase flexibility, safety and performance.

EVERETT, WA -- Fluke Corporation, the global leader in portable electronic test and measurement technology, has introduced the industry's most advanced, capable and comprehensive family of clamp meters, designed to meet every requirement for testing and maintaining electrical systems, industrial equipment and controls, and commercial and industrial heating, ventilation and air conditioning (HVAC) equipment.

With this new family of clamp meters, Fluke provides a range of state-of-the-art features to meet even the most demanding requirements for flexibility, safety and performance.

These revolutionary and innovative test tools include:

  • Fluke 381 Remote Display True-rms AC/DC Clamp Meter, a full-featured meter that features the industry's first detachable display.
  • Fluke 376 True-rms AC/DC Clamp Meter is designed for testing large industrial motors and other high current applications in the toughest industrial environments. The Fluke 381 and Fluke 376 are shipped with the new Fluke iFlex flexible current probe (see below).
  • Fluke 374 and 375 True-rms AC/DC Clamp Meters measure both ac and dc current. The Fluke 375 is designed for use with common motors and drives below 600A. Its low pass filter and ability to measure mV dc make it ideal for industry. The Fluke 374 measures both ac and dc current, which is important for security systems, basic motors and uninterruptible power supply systems.
  • Fluke 373 True-rms AC Clamp Meter - General purpose clamp meter offers durability and accuracy for great value.
  • Fluke iFlex Flexible Current Probes expand the measurement range of compatible Fluke meters to 2500 A ac with ultimate measurement flexibility. The large coil reaches around large conductors and fits between tightly-packed cables. A six-foot cord allows measurement at a distance for easier viewing.

Every clamp meter in the family is improved: They feature thinner, smaller jaws for easier use inside crowded equipment cabinets, large backlit displays, true-rms standard and improved overmolding for easier handling and improved survival if dropped.

Safety ratings too are improved. The Fluke 381, 376, 375, 374 and iFlex current probes are rated for safe use in hazard category IV (CAT IV) 600 V environments (CAT IV 600 V, CAT III 1000 V) as defined by safety regulators in the US, Canada and Europe. The Fluke 373 is rated CAT IV 300 V, CAT III 600 V. A rating of CAT IV 600 V is required for use in outdoor environments.

The new Fluke family of clamp meters includes:

Fluke 381 Remote Display True-rms AC/DC Clamp Meter—The Fluke 381 is a full-featured clamp meter with an important extra; users can remove the detachable wireless display for even more flexibility, convenience and safety. One technician can do jobs that used to require two people: clamp the Fluke 381 around a conductor, remove the display, then close the equipment cabinet or move across the room to operate controls. US list price is $498.95.

Fluke 376 True-rms AC/DC Clamp Meter with iFlex—With the new Fluke 376 Clamp Meter, users will be ready for any measurement challenge. Designed for the toughest industrial environments, it measures current up to 2500 A ac and 1000 A dc and can troubleshoot even the noisiest motors and drives. With true-rms ac voltage and current measurements, min/max/average and inrush recording, the Fluke 376 can read up to 1000 V and 1000 A in both ac and dc modes. The Fluke 376 includes the new iFlex flexible current probe. The Fluke 376 is the direct replacement for the Fluke 337. US list price $374.95.

Fluke 374 and 375 True-rms AC/DC Clamp Meters—The new Fluke 374 and 375 clamp meters offer improved performance perfect for many current measurement situations. With true-rms ac voltage and current measurements, the Fluke 374 and 375 can read up to 600 V and 600 A in both ac and dc modes and handle min/max, average and inrush recording. Both are compatible with the new iFlex flexible current probe (sold separately). Ideal in an industrial environment, the Fluke 375 also comes with R Range, frequency to 500 Hz, mV dc, and integrated low pass noise filter. US list price for the Fluke 375 is $299.95; for the Fluke 374, $259.95.

Fluke 373 True-rms AC Clamp Meter—The new Fluke 373 basic clamp meter offers improved performance and maximum value for price-sensitive users. It is perfect for many ac-only current measurement applications. With true-rms ac voltage and current measurements and inrush, the Fluke 373 reads up to 600 A ac and 600 V ac or dc. US list price $179.95.

iFlex i2500-18 and i2500-10 Flexible Current Probes—The new Fluke iFlex flexible current probes expand the measurement range of the select Fluke meters to 2500 A ac while providing the ultimate measurement flexibility. The iFlex probes connect directly to the meter, displaying current measurements without error-prone scaling factors. The large coil allows users to reach around large or awkward-shaped conductors, while the small 0.3 inch profile allows the coil to reach between tightly-packed cables and improves access in crowded spaces. Their six-foot cord allows measurement at a distance from the conductor, making it easier to view the readings. Available in 25 cm (10 in) and 45 cm (18 in) sizes and included with the Fluke 381 and Fluke 376 Clamp Meters; compatible with Fluke 375 Clamp Meters. US list price, either model, is $98.95.
