MC-7355 Split ultrasonic hole (groove) quality tester





Comparative advantages of MC-7355 new and old ones:
1. Small size, light weight, easy to move and unload, and low transportation cost;
2. Reduce personnel hole top operations to avoid personal safety risks. The winch can be detected when placed on the vehicle;
3. One-click fully automatic detection can be used without professional training to avoid deviation in results caused by newly deployed equipment personnel who cannot operate;
4. The testing speed can reach 30 meters/minute, and the testing efficiency is greatly improved;
5 The raw data is stored in the probe. You can use a tablet computer or mobile phone to directly read the raw data in the probe and upload it to the platform for permanent storage to ensure data safety and reliability;
6. Modular design, cable-free design, convenient maintenance;
7. Diversified power supply methods (support connection to electric vehicle power supply and car cigarette lighter power supply) to adapt to different on-site operating conditions;
8. The digital twin platform synchronizes the scene and controls hole forming data in real time;
9. The standby time is long, and the probe can last for up to 25 hours.
10. The single roller design can measure small aperture and small blind area.
