testo 862-2 Electrical Kit - Thermal imager (256 x 192 pixels) and clamp meter

The testo 862-2 Electrical Kit is a cutting-edge diagnostic tool that wirelessly connects the testo 862-2 thermal imager with the testo 770-3 TRMS clamp meter. By integrating thermal imaging with advanced electrical measurements, this kit delivers a perfect approach to system diagnostics, ideal for HVAC/R technicians, electricians, and facility managers.

The testo 862-2 produces high-resolution thermal images (256 x 192 pixels) to pinpoint temperature variations and potential hotspots, while the testo 770-3 clamp meter delivers accurate measurements of current, voltage, and resistance to give context to the thermal image. This synergy not only enhances diagnostic precision but also minimises troubleshooting time.

To further improve efficiency in the field, the testo 862-2 offers smart features such as alarm functions, hot/cold spot detection, and automatic Delta T calculation.

Built for field use, both instruments feature robust construction with IP54-rated protection and 1.5m drop resistance, ensuring reliable performance in demanding environments.
