Application

Electromagnetic cover meters can be used for:

• Quality control, to ensure correct location and cover to reinforcing bars after concrete placement;
• Investigation of concrete members for which records are not available or need to be checked;
• Location of reinforcement as a preliminary to some other form of testing in which reinforcement should be avoided or its nature taken into account, e.g. extraction of cores, ultrasonic pulse velocity measurement or ‘near to surface’ methods;
• Location of buried ferromagnetic objects other than reinforcement, e.g. water pipes, steel joints, lighting conduits.
