Fluke 707Ex Intrinsically safe loop calibrator




Product Description

Fluke 707Ex Intrinsically safe loop calibrator

  • Large display and simple, quick-click push rotary button for easy one-handed operation
  • Simultaneous mA and % readout for quick, easy, interpretation of readings.
  • mA accuracy of 0.015%, superior to other loop calibrators
  • 1 µA resolution for mA source, simulate and measure
  • Push button with 25% steps for fast, easy linearity checks
  • 0-100% “span check” for fast confirmation of zero and span
  • Selectable slow ramp, fast ramp, and step ramp to provide smooth outputs for valve slewing and loop functional tests
  • Internal loop supply, so you can power and read a transmitter at the same time without carrying a DMM
  • Measures Vdc to 28 V
  • Single 9 V battery that is easily changed
  • 0-20 mA or 4-20 mA default start up modes
  • Innovative output adjustment dial with 1 µA and 100 µA resolution
  • HART® compatible resistance is connected in series with the loop supply for compatibility with HART communicators
