Ferroscan test

Ferro Scan test and covermeter

Ferro scan test or Electromagnetic cover measurement is one of nondestructive test for determine position and quantity of reinforcement steel inside concrete member. Most of old building doesn’t have structural drawing or out of date drawing after renovation. So Ferro scan test able to use for inspect RC member compare with existing data.

Ferro scan machine use electromagnetic field principle. The emitter head releases electromagnetic field and when we move emitter head close to reinforcement area, reinforcement bar as induction properties will be disturbing electromagnetic field. The area where is disturbed mostly able to determine as reinforcement steel location.
