Multi-Color Dynamic Imaging
The multi-color dynamic imaging function allows users to highlight a specific target area in color within a real-time thermal image through touch control, while displaying the surrounding areas in grayscale. This enhances the visualization of subtle temperature differences in complex inspection environments, making it easier to identify defects associated with minor temperature variations during on-site diagnostics.
Visible-Light Temperature Measurement
An intelligent focusing system automatically aligns the thermal and visible-light images at different inspection distances, improving the practicality and accuracy of visible-light temperature measurement.
Continuous autofocus technology maintains a clear focus of the infrared thermal image across different inspection positions and distances, helping achieve more accurate temperature measurement and reliable on-site thermal inspection results.
