Product Description

Overview

The function and range settings are always correct because the measurement parameters are detected and set automatically. Three easy-to-read buttons replace the traditional rotary switch when selecting manual test functions. The 770 series of instruments are rich in the features HVAC techs need and want including TRMS, starting current, and frequency measurement.

The 770-3 additionally includes real-time power measurements (Watts), Power Factor, and Bluetooth.  The Testo App can be used for remote viewing, monitoring trending over time, and creating reports. The powerful app allows you to create custom reports that include photos, data, and graphs that can be saved or sent via email.
