    Fluke 789 Process Calibrator (Hire Only)

    This model is available for hire. Please see the Process Calibrator Hire page for more information.

    Typical Applications:

    Features:

    • Measures AC/DC voltage to 1000V
    • Measures AC/DC current to 440mA
    • Measures resistance to 40MΩ
    • Measures frequency to 20kHz
    • Current sourcing and simulation from 0 to 20mA
    • HART mode and multiple step options

    The Fluke 789 Process Meter can measure a multitude of electrical parameters in addition to sourcing current in order to calibrate process loops. The meter boasts measurement for AC/DC voltage, AC/DC current, resistance, and frequency as well as continuity and diode testing. There is also a zero function, min/max/avg recording and display hold whist true RMS measurement helps safeguard accuracy on AC values.

    A 24V loop power supply allows a source current of between 0mA and 20mA to pass through resistances of up to 1200Ω and various ramp options include min/max toggling, auto-ramp, auto-step and four separate manual step options. The calibrator is also compatible with HART instruments.

    Part number: HPRO.3
