Humboldt Concrete Rebound Hammer H-2987H
Humboldt's H-2987H concrete rebound hammer provides a reliable, yet economical, alternative to the original schmidt hammer. It is a fast non-destructive way to test the in-place strength of concrete in structures, such as buildings, bridges, commercial structures, and pre-cast panels. The unit supports the following standards: ASTM C805, BS 1881: PART 202, ISOIDIS8045, ENV 206, IGJ/T 23-2001 Rebound values are displayed on a mechanical sliding scale. These values can then be correlated to compressive strength by using the conversion table chart affixed to the hammer. It includes a grinding stone, a cloth carrying case, instruction booklet and conversion charts.
