// Features

Professional-grade tools for your bench

Built for electronics engineers who need accurate, actionable thermal data — not consumer gimmicks.

Live Thermal View

Real-time calibrated thermal imaging from your USB camera. Full-frame streaming with configurable color palettes to reveal temperature gradients the moment you point the camera.

Accurate Temperature Readout
