A Leading Innovator in State-of-the-Art Measuring Technology
Automatically detect direct and alternating voltage with this non-contact True RMS clamp meter featuring fully retractable pincer arms designed for tight application environments. Moreover, use the Bluetooth® capability to connect to the Testo Smart App and other measuring instruments for enhanced data and reports functions.
Automatically detect direct and alternating voltage with this non-contact True RMS clamp meter featuring fully retractable pincer arms designed for tight application environments. Moreover, use the Bluetooth® capability to connect to the Testo Smart App and other measuring instruments for enhanced data and reports functions.
The most powerful model in the clamp meter series, the testo 770-3 calculates all output ratings and contains a Bluetooth interface that increases the instrument’s flexibility to collect more data at once to diagnosis common problems or electrical connections. With this clamp meter, technicians are able to connect to compatible instruments with the Testo Smart App to show the measurements as a graph or to document it directly in a report it offers lots of additional functions for those challenging tasks that you are faced with daily, e.g. communication with the testo smart app via Bluetooth.
Ideal for current and voltage measurements in compact heat pumps and mini split systems, this clamp meter features an innovative slide clamp design for safer wire testing in tight spaces, especially when working with thermistors and control panels. Automatic measurement parameter recognition ensures accurate voltage measurements, eliminating guesswork and enhancing safety. The rotary dial allows for additional measurements such as resistance, continuity, diode, and capacitance, reducing the need for multiple instruments in your toolkit.
