Overview
TN660 is an online fixed-mount thermal camera engineered for high-speed dynamic temperature measurement in industrial environments. It integrates a 640×512 uncooled VOx detector with 12 μm pixel pitch and supports 120 Hz full-frame output to enable synchronized high-rate thermal imaging and temperature data capture.

Short product summary
