Proceq Rock Schmidt Rebound Hammer, Type N
Rock Schmidt Test Hammer measures the hardness, strength, and consistency of rock formations for the evaluation of engineering and geological properties. Rebound values assess age and weathering or estimate penetration rates for tunnel boring machines and rotary drum cutters. The Rock Schmidt Test Hammer meets ASTM D5873 requirements and features intuitive menu-guided operation, electronic data processing, automatic correction for testing positions, and test data storage.
Data management and information-sharing features are optimized through the Schmidt Live app, a free download for Apple iOS and Android devices. The iOS version features text-to-speech operation for rapid and efficient test logging. Connection to a web-based reporting tool via Bluetooth enables real-time sharing of test data. A logbook feature allows GPS positioning, notes, images, and audio comments to be added to the reports. The app also allows for instantaneous report generation in PDF and CSV formats.
Rock Schmidt Test Hammers have a memory capacity for up to 20,000 measurements. Electronic processing of rebound and impact velocities maximizes accuracy and repeatability. Estimated battery life for 20,000 or more impacts between charges. The HM-82R Rock Schmidt Test Hammer is effective for rock with compressive strengths from 2,900 to 21,750psi (20 to 150MPa) and has an impact energy of 2.207Nm (1.63ft-lbf). See HM-82RL for a model with an impact energy of 0.735Nm (0.54ft-lbf) for formations less than 4in (100mm) thickness.
