  • The Fluke 705 loop calibrator is a cost-effective, integrated solution for calibration, repair and maintenance of milliamp loops. It features:

    • mA sourcing, simulation and measurement
    • 0.02% accuracy and 0.001 mA resolution
    • Simultaneous mA and % of span display
    • Selectable step or ramp outputs
    • 24 V Loop supply with mA measure
    • 0-28 VDC measurement to check Loop Voltage
    • Easy battery exchange without opening the case
    • Compact case with separate protective holster
    • Three year warranty
  • Low cost calibrator muscle.

    For a powerful loop calibrator at a very affordable price, choose the Fluke 705 Loop Calibrator. This feature-rich solution to loop calibration, maintenance and repair offers:

    • A large display and simple, pushbutton interface for ease of use.
    • Simultaneous mA and % readout for quick, easy interpretation of readings.
    • mA accuracy of 0.02%
    • Push button 25% steps for fast, easy linearity checks. Save time over traditional knob type controls.
    • "Span Check" for fast confirmation of zero and span.
    • Selectable slow ramp, fast ramp, and step to provide smooth outputs for valve slewing and loop functional tests.
    • 24 volt internal loop supply, so you can power and read a transmitter at the same time without carrying a DMM.
    • Single 9V battery that is easily changed.
    • 0 - 20 mA or 4 - 20 mA default start up modes.
