Fluke 376 Clamp Meter Max Current 2.5kA ac, 999.9A dc CAT III 1000 V,CAT IV 600 V

Product Details
Fluke 376 True RMS AC/DC Clamp Meter with iFlex. The Fluke 376 clamp meter offers improved performance for a wide range of current measurement situations. 

With True RMS voltage and current measurements, the Fluke 376 can read up to 1000 V and 1000 A in both ac and dc modes. The new 18 in (458 mm) iFlex flexible current probe is included. It expands the measurement range to 2500 A ac while providing increased display flexibility, the ability to measure around awkward-sized conductors, and improved wire access. The Fluke 376 is the direct replacement for the Fluke 337 clamp meter.

Features & Benefits

  1. Large backlit display
  2. 1000 A ac and dc current measurement with fixed jaws
  3. 2500 A ac current measurement with iFlex flexible current probe
  4. 1000 V ac (True RMS) and dc voltage measurement
  5. 500 mV dc measurement range to interface with other accessories
  6. Frequency, capacitance, resistance, and continuity measurement
  7. Display HOLD, Min, max, average, and inrush recording
  8. Low pass filter for stable readings in noisy environments
  9. CAT IV 600 V, CAT III 1000 V safety rating
