Powerful, practical, and precise

Meet the Klein Tools NCVT-4IR, a compact professional-grade tool built for HVAC work and on-site diagnostics. It combines a non-contact voltage tester with an infrared thermometer, so you can verify live circuits and measure surface temps in one hand-friendly device.

Voltage detection covers 12 to 1000 V AC with clear visual and audible indicators, helping you confirm presence without contact. The IR thermometer offers a 4:1 distance-to-spot ratio and a measurement range of -22 to 482 °F (-30 to 250 °C), with units you can toggle to suit your workflow. A laser pointer helps you target the measurement area even in dim projects.
