Description
H-2987H
Humboldt Concrete Rebound Hammer
Supports the following standards:
ASTM C805, BS 1881: PART 202, ISOIDIS8045, ENV 206, IGJ/T 23-2001
Humboldt’s concrete rebound hammer provides a reliable, yet economical, alternative to the original Schmidt hammer. It is designed for testing concrete 4″ (100mm) or more in thickness with a maximum particle size less than or equal to 1.25″ (32mm), providing a quick and simple test for obtaining an immediate indication of concrete strength in various parts of a structure.
The Humboldt rebound hammer covers a compressive strength range of 1,450 to 9,000 psi (10 to 62 MPa). To operate, the rebound hammer is pressed against the concrete structure and the 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.
The instrument includes:
- (1) H-2975.27 – Grinding Stone,
- (1) Cloth carrying case,
- (1) Instruction booklet
- (1) conversion charts.
Replacement conversion chart for rebound hammers (sold separately).
Conversion Chart Labels:
- H-2987H.7 – Conversion Chart Label (psi/MPa)
- H-2975.25 – Conversion Chart Label (psi)
- H-2975.25N – Conversion Chart Label (N/mm2)
