Soil Compaction Analyzer

The Rainhart Soil Compactor Analyzer measures, monitors, controls, and provides quality insurance all in real time for Proctor and modified proctor testing. Exclusively compatible with the Rainhart Soil Compactor, the SCA is quickly and easily mounted on top of the Proctor Compactor. Once installed the SCA will automatically control the start and stop of the Soil Compactor ensuring the correct amount of energy is always delivered to the sample. While in use all data is then instantly displayed on the monitor in real time to provide good correlation with lab calculated soil moisture-density values. The SCA simultaneously calculates test parameters by using rapid sampling the rammer's position, velocity, and known mass to determine the impact energy being imparted to the specimen, per blow, per lift. The Rainhart SCA is the only SCA on the market approved by TxDOT for the TEX-113E analysis of soil compaction testing.
