Electrical Measuring Pliers – Testo 770-3

The testo 770-3 clamp ammeter is ideal for demanding measurement tasks in tight space applications. The pincers can be fully retracted, allowing the device to grab tightly packed cables with exceptional precision.

Introducing testo 770-3 electrical measuring pliers

More specialized applications can be handled using the testo 770-3, such as inrush current, power and µA measurement. Temperature adapter (order option) for thermocouple probe can be used to measure electrical parameters as well as temperature.

Clamp-on ammeter automatically detects, selects AC/DC current and other parameters, such as resistance, continuity, diode, capacitance, etc. This makes your testing and measurement easier and more reliable than ever. Your measurement values can be clearly presented via the 2-line display.

In addition, the testo 770-3 offers a performance measurement function and can be connected via Bluetooth to the testo Smart app. In the App, measurement data can be displayed as graphs and recorded directly in reports.
