The Rainhart Proctor Soil Compactor is the most versatile and advanced soil compactors in the industry. The compactor is designed for high volume testing, low maintenance, and high efficiency. The Rainhart Proctor’s signature circular pattern automatically delivers blows relative to the specimen height, avoiding adjustments between specimen layers. The tamping head revolves around the sample instead of the sample revolving around the tamping head, which produces more accurate results and shorter cycle times. All Rainhart tamping heads are all interchangeable with a single shaft, eliminating the need for additional costly parts.

With a comprehensive list of accessories including tamping heads, molds, perforated base plates, and finishing tools, the Rainhart Soil Compactor can perform any soil compaction test and is the only soil compactor compatible with the SCA.
