Huajingkang's online infrared thermal imager adopts an imported 17µm uncooled infrared focal plane detector. It has a temperature measurement range from -20℃ to 3000℃, and the temperature measurement accuracy can reach ±2℃ (or ±2%). The software application can flexibly conduct thermal characteristic - related analysis and raw data collection. It is the first - choice device for optimizing the process control of heat sources such as laser welding and 3D printing.
