Testo 770-2 Clampmeter


Testo 770-2 is suited for current measurement in switching cabinets. One of the two pincer arms can be fully retracted into the instrument. This unique mechanism means that cables in tight switching cabinets can be easily grabbed. The automatic measurement parameter detection also enables reliable work. Testo 770-2 detect direct and alternating current and select other parameters such as resistance, continuity, diode and capacitance automatically. The clamp meter also has a μA range as well an integrated temperature adapter for all type K thermocouples.

Benefits

No more problems grabbing cables in confined spaces
Grab cables with the clamp instead of touching them
Clear visible measurement results

Standards

EN 61326-1, EN 61140

Approvals

TÜV, CSA, CE

Supplied with

Testo 770-2 TRMS clamp meter, batteries, 1 set of measuring cables and 1 x adapter or type k thermocouples.
