Feature
- Function of echo-echo measurement is available. It is used for measuring the distance between echo to echo, and thus users will get to know the thickness of steel plate even though it is covered by coating, such as inspection of oil tanks.
- Min. and Max. mode function is supplied for users to find out the Min. (or Max.) value from a group of measuring results. it is very useful for inspecting the wall thickness of pipes and pressure vessels.
- Manual gain adjustment / auto gain selectable.
- Up and low limits alarm is available.
- D-value mode function. It comprises normal D-value mode and percentage D-values mode. It will enhance operator's working efficiency greatly. Specially, users
- working with exact and changeless process requirements will benefit from TT500 immensely.
- Large memory up to 100 A-scan images and 10000 thickness values.
