Fluke 355 True RMS Clamp Meter

The Fluke 355 features a large opening fixed jaw, capable of measuring AC/DC current up to 2000A. The 58mm jaw design makes the Fluke 355 suitable for large or multiple conductors. Despite being bigger than most standard clamp meters, the Fluke 355 is still easy to operate with one hand and whilst wearing PPE.

There is an inrush feature to capture accurate peak measurements, as well as MIN / MAX and Average. The Fluke 355 also has True RMS voltage and current measurement, for accurate readings even on noisy circuits. The 355 also measures voltage and resistance, making this an ideal clamp meter for utilities, electrical contractors and industrial service technicians.

Fluke 355 key features:

  • Reliably handle a wide range of high-current applications with 2000 A ac + dc true-rms, 1400 A ac, and 2000 A dc
  • The large 58 mm (2.3 in) jaw capacity is suitable for large or multiple conductors
  • CAT IV 600 V, CAT III 1000 V rating for added user protection
  • In-rush current measurement captures 'power-on' surge current with accuracy and repeatability
  • High voltage measurement of 1000 V ac + dc true-rms, 600 V ac, and 1000 V dc allows the user to perform multiple tests with only one tool
  • Resistance to 400K ohms coupled with a continuity beeper provide the convenience of a multimeter in a clamp meter.
  • Accurately measure frequency up to 1 kHz for optimum troubleshooting
  • Quickly analyze readings using the MIN, MAX, and AVG functions
  • A large backlit display allows for easy visibility in low-lit areas
  • Use the display hold feature to capture readings even when the display cannot be viewed
  • Use the low-pass filter to smooth out noisy loads and stabilize readings
