Protovale’s CM9 CoverMaster is a microprocessor instrument for testing concrete structures. It simultaneously gives the accurate location of rebars, the measurement of concrete cover, and bar diameter. It will also give the correct depth of cover when the bar size is unknown or has been incorrectly selected by the operator. The CM9 can be used in poorly lit areas such as the soffit of a bridge as it has a backlight in the display screen and bright LED in the search head.
