The three instruments in the testo 770-3 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.
770-3 also has a μA range as well as an integrated temperature adapter for all type K thermocouples.
770-3 includes real-time power measurements (Watts), Power Factor, and Bluetooth. The free Testo Smart Probes App can be used for remote viewing, monitoring, data logging, and creating reports via Bluetooth. The powerful app allows you to create custom reports that include photos, data, and graphs that can be saved or sent via email.
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.
