Electrical Inspection Kit

The Electrical Inspection Kit is a cutting-edge diagnostic tool that harnesses the complementary strengths of the testo 860i Wireless Thermal Imaging Camera and the testo 770-3 Clamp Meter. By integrating thermal imaging with advanced electrical measurements, this kit delivers a perfect approach to system diagnostics, ideal for Electrician, HVAC technicians, Facility Maintenance, and building inspectors.

The testo 860i produces high-resolution thermal images (256 x 192 pixels) to pinpoint hotspots and measure Delta T of potential problems, while the testo 770-3 clamp meter delivers accurate measurements of current, voltage, and resistance. Their seamless connectivity via the testo Smart App enables real-time data synchronization, allowing professionals to quickly correlate thermal anomalies with electrical load. This enhances diagnostic precision and minimizes troubleshooting time, leading to more efficient evaluations.

Built for field use, both instruments feature robust construction with IP54-rated protection and 1.5m drop resistance, ensuring reliable performance in demanding environments. The unified reporting and documentation capabilities of the testo Smart App further streamline workflows by simplifying the analysis, recording, and sharing of critical data on-site. Whether diagnosing electrical faults, assessing HVAC systems, or inspecting building structures, the testo 860i Electrical Kit provides a versatile, efficient, and dependable solution that maximizes the benefits of combined thermal and electrical analysis.
