A high-performance grinding bit (18 mm in diameter) attached to a grinding machine, pulverizes the concrete into a fine powder at exact depth increments, which can be selected between 0.5 mm to 2.0 mm. The grinding area is 73 mm in diameter and the maximum depth is 40 mm.
For every depth increment of 1 mm, approximately 9 grams of powder is obtained for analysis. It takes 4 to 6 minutes to obtain each sample and about 5 minutes to determine the chloride content using the RCT Kit.
For in-situ testing, the Profile Grinder can be attached to horizontal or vertical surfaces using the anchor bolts and clamping pliers.
