SPTMAN Hammer Energy Tester

SPTMAN Hammer Energy Tester

The SPTMAN Hammer Energy Tester is a rugged, portable system designed to accurately measure the energy transferred from a drive hammer to the drive rods during Standard Penetration Tests (SPT). It calculates the actual hammer energy coefficient by comparing measured energy with the theoretical potential energy. This system is essential for validating and calibrating SPT equipment to ensure compliance with industry standards such as BS EN ISO 22476-3 and ASTM D4633-10.

Key Features of SPTMAN Hammer Energy Tester

Accurate Energy Measurement: Measures the actual energy transferred by the SPT hammer to the drive rods. Calculates the hammer energy efficiency (% energy transfer), as per ASTM D4633 and EN ISO 22476-3 standards.
