Rock Schmidt Type L Test Hammer features low-impact energy for improved repeatability and minimal damage in geological applications evaluating weak or porous rock formations and those with thin weathering crusts. The Type L Rock Schmidt determines hardness, strength, and consistency data for the evaluation of engineering properties. The Rock Schmidt meets ASTM D5873 requirements and features intuitive menu-guided operation, electronic data processing, automatic correction for testing positions, and test data storage. Estimated battery life for 20,000 or more impacts between charges.
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. Electronic processing of rebound and impact velocities maximizes accuracy and repeatability.
Features:
- Fast and cost-effective condition assessment of geological formations
