The Testo 770-3 clamp meter simplifies non-contact measurements in tightly packed cables. Its innovative grab mechanism allows easy access, even in confined spaces. As the most powerful model in the clamp meter series, the Testo 770-3 offers unique features. Additionally, it provides increased resolution, especially in the lower current range, ensuring precise measurements.
The Testo 770-3 clamp meter is perfect for demanding measurements in tight application environments. Its fully-retractable pincer arm allows precise selection and measurement of tightly packed cables. It also has an extended voltage measurement range of up to 1000V to cover even further applications.
The clamp amperemeter automatically detects and selects AC/DC and other parameters, such as resistance, continuity, diode and capacitance. In addition, more specialised measurements can be handled using the clamp meter, such as starting current, power and µA measurements.
The Testo 770-3 clamp meter displays measurement values on its two-part display and in the Testo Smart App. Via Bluetooth, it seamlessly connects to other Testo measuring instruments. In the app, you can view the measurement curve graph on your smartphone or tablet and conveniently save and send readings in your report.
The premium kit includes TC-type K temperature probes, crocodile clips, micro clips and a magnetic holder for your measurement device.
