DEMA70C Magnetic Crawler EMAT Thickness Measurement System
No need scaffolding, no need remove scale, rust or paint. No need couplant. It can realize rapid detection of high altitude wall thickness corrosion through remote control system.
Product Features：
- 2-wheel freestyle motion, reliable attachment. Capable of climbing up to 50 meters from grand level.
- Install electromagnetic ultrasonic thickness probe for rapid screening and positioning against wall erosion.
- Accurate Scanning the area to test the thickness corrosion.
- Matching A scan and B scan display.
- Equipped with video camera, the video situation of the inspected surface can be observed in real time.
- The remote control system controls the scanning direction and can preset the scanning direction.
- High temperature function (optional): over-temperature warning and protection functions. It can take thickness readings on high temperature surface up to 150℃/302F thanks to EMAT sensor and high-temp magnet.
