Testo 770-3 Cable-Grab Clamp Meter
Couldn't load pickup availability
- Easy to operate thanks to the fully retractable pincer arm
- Auto AC/DC and large two-line display
- Improved TRMS method
- Bluetooth connection to your smartphone (with the Testo Smart App)
Non-contact measurement on tightly packed cables is really easy and reliable with the Testo 770-3 clamp meter. Its innovative grab mechanism will make your work easy. The most powerful model in the clamp meter series, it offers lots of additional functions for those challenging tasks that you are faced with on a daily basis, e.g. communication with the Testo smart app via Bluetooth.
Overview
The three instruments in the testo 770 clamp meter family are ideally suited for current measurement in switching cabinets. One of the two pincer arms can be fully retracted into the instrument. This unique grab mechanism means that cables in tight switching cabinets can be easily grabbed. The automatic measurement parameter detection also ensures reliable work: in the current and voltage area, all three instruments detect direct and alternating current and select other parameters such as resistance, continuity, diode and capacitance automatically.
