Concrete Test Hammers
HM-82 Rock Schmidt Test Hammer is designed for geological applications and provides hardness, strength and consistency data for evaluation of engineering properties as well as geomorphology characteristics like age and weathering. Rebound values can be used to predict penetration rates for tunnel boring machines and rotary drum cutters. 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. The included RockLink software has functionality for downloading to user’s computer for analysis and reporting, the ability to create custom strength correlation curves for unconfined strength and memory capacity for up to 400 test series. Electronic processing of rebound and impact velocities maximizes accuracy and repeatability. Estimated battery life allows 5,000 or more impacts between charges.
Features:
- Fast and cost-effective condition assessment of geological formations
