HTH-225E Digital Concrete Compressive Strength Test Hammer
1.Introduction
HT-225E Digital Concrete Hammer is a high-tech product, especially designed for the needs of in place test for concrete compressive strength, applied to non-destructive test (NDT) hardened concrete compressive strength component in construct projects.
Digital Test Hammers for the quick and easy determination of the strength of concrete, and hardness of construction materials. Digital functions allow faster and greater number of test, leading to better quality tests. It’s a good and useful instrument for quality control and inspection organizations. Its power source is 5# Ni-MH rechargeable battery available worldwide.
