The Cordix 3010 b thickness gauge is engineered with a rigid frame that is made of a special light alloy that fits conveniently into the operator's hand. This feature eliminates fatigue when operating, even for long periods of time. This unit is fitted with a dial gauge and probe that are both anodized with nickel, and an enamel coated frame. A unit's shape is dictated by the hardness of the material tended.
