Schmidt Hammers

Most versions of rebound hammers are divided into two types, based on the impact energy they produce. Both are effective on concrete mixes with a similar range of compressive strengths. Rock Schmidt Hammers are designed with specific geological and geotechnical capabilities.

Type N Schmidt Hammers Comparison Chart

  • Schmidt Type N Test Hammers are often considered as the “standard” models and have a higher energy output to test a wide range of concrete elements and structures 4in (100mm) or more in thickness.
  • Schmidt Type L Test Hammers have lower impact energy and provide more repeatable values when testing items less than 4in (100mm) in thickness. Ideal for thinner sections like precast pipe or early-age concrete for form removal or post-tensioning operations, Type L concrete hammers also reduce both cosmetic and structural damage to concrete with thin cross sections.
