Current Measuring Instruments

The three instruments in the testo 770 clamp meter family are ideally suited for current measurement in switching cabinets. Both instruments in the testo 755 current/voltage tester family are the first of their kind: voltage testers which meet the latest standard and which can also measure current. This means they are suitable for virtually all daily electrical measuring tasks.

  • testo 770-3 - Hook clamp and power meter with Bluetooth

    Order-Nr. 0590 7703

    The testo 770-3, in addition to the features of the other meters in the testo 770 series, includes real-time power measurements (Watts), power factor, and Bluetooth. The Testo app can be used for remote viewing, monitoring, data logging, and creating reports. This powerful app allows you to create custom reports that include photos, data, and graphs that can be saved, or sent via email.

    • Unique hook-on function separates and grabs wires, without using your hands, and the retractable post makes hook release in tight spaces fast and easy

    • Bluetooth, coupled with the free testo Smart Probes app, works with smartphones and tablets for remote viewing, data logging, and report creation

    • Real-time power measurements (Watts), with simultaneous power factor indication  

    • μA parameter for flame rod (ignition flame sensor) testing, and temperature measurement using optional type K thermocouple adapter

  • testo 770-2 - Hook clamp meter with thermocouple adapter

    Order-Nr. 0590 7702

    In addition to the standard functions of the testo 770-1 hook clamp meter, the testo 770-2 includes a thermocouple adapter, and measures microamps.

    • Unique hook-on function separates and grabs wires, without using your hands

    • Retractable post makes hook release fast and easy

    • Meter automatically identifies testing in-process, and selects the correct meter configuration, to save time and optimize accuracy

  • testo 770-1 - Hook clamp meter

    Order-Nr. 0590 7701

    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.

    • Unique hook-on function separates and grabs wires, without using your hands

    • Retractable post makes hook release fast and easy

    • Meter automatically identifies testing in-process, and selects the correct meter configuration, to save time and optimize accuracy

    • Inrush (starting) current capture, APO (Auto Power Off), and Min / Max / Hold

  • testo 755-2 - Current / Voltage Meter with 200 A AC, 1000 V AC/DC, Continuity, and Phase Rotation Tester

    Order-Nr. 0590 7552

    The testo 755-2 includes important additional features: phase rotation, voltage range up to 1000V, and the unique feature which allows the user to check for voltage using only a single lead.  The testo 755 current/voltage testers are fast and easy to use, especially when you are testing many circuits. The convenient open-jaw current tester automatically turns on when voltage exceeds 6V. It then auto-selects the correct parameters and range for your test. These rugged testers are suitable for virtually all your daily electrical measuring tasks.

    • Phase rotation tester and voltage range up to 1000 V
