    Product Description

    testo 770-1 - Hook clamp meter

    Description

    The testo 770 series identifies the testing in-process and automatically selects the correct meter configuration, which saves you time and increases your accuracy.

    The testo 770 series of instruments is rich in the features HVAC techs need and want, including TRMS, starting current, and frequency measurement.

    Delivery Scope

    testo 770-1 hook clamp meter 400 A, including test leads, 3 AAA batteries, instruction manual, quick start guide, and certificate of conformity
    Your advantages
    • Unique hook-on function separates and grabs wires, without using your hands
    • Retractable post makes hook release fast and easy
    • Inrush (starting) current capture, APO (Auto Power Off), and Min / Max / Hold
    The testo 770-1 hook clamp meter is ideally suited for electrical work in HVAC applications. Testo’s unique hooking clamp design can be used to separate and grab wires. The easy hook-off retractable post releases the wires when testing in tight spaces. You can safely work without using your hands.
