The P50D Chimney camera is designed to reach and inspect hard to access launch points to camera tiny flaws and defects. It can be used to detect chimneys,air ducts and flue liners,with special design to allow operaters to record defects of these objects and structures to avoid unnecessary digging and complex disassemble,and help facilities' owners to monitor the present condition and prevent potential damages.With ultra-bright led lights,the system can ensure well proportioned and shadowless illumination despite the original inspection condition.And thanks to upright picture control technology,the camera always provides upright image while the operater pan or tilt the camera head to focus on defects.
