Original Schmidt Digital Rebound Hammer, Type N

Original Schmidt Digital Rebound Hammer, Type N

Introduction

In the construction industry, ensuring the durability and safety of concrete structures is paramount, and accurate assessment of concrete strength is a critical part of this process. The digital concrete test hammer, also known as a test hammer, has become a widely trusted instrument for evaluating the compressive strength of concrete surfaces quickly and efficiently. Utilizing a spring-loaded mass that impacts the concrete, this device measures the rebound distance to estimate the compressive strength of concrete without causing any damage to the material.

The concrete test hammer is a non-destructive method that allows engineers, contractors, and quality control professionals to assess and determine the strength and uniformity of concrete in a matter of seconds. The digital rebound hammer stands out for its high testing accuracy, ultra-low power consumption, and easy operation, making it an essential tool for concrete strength testing on job sites and in laboratories alike. With the ability to automatically record and store test data, these instruments provide reliable readings and consistent results, streamlining the procedure and supporting further analysis.

By offering a fast, accurate, and convenient way to estimate the compressive strength of concrete, digital concrete test hammers help ensure the quality and safety of construction projects. In this article, we will explore the features, benefits, and applications of digital rebound hammers, delve into the test procedure, and highlight the advantages of using this advanced device for concrete compressive strength testing.

Concrete Test Hammers

Original Schmidt Live Concrete Test Hammer makes concrete strength estimation and uniformity assessment more accurate, repeatable, and efficient. Offering the same compressive strength range and impact energy as the classic Original Schmidt Type N model, the Schmidt Live adds digital functionality, a rugged, fiber-reinforced shell, and cloud-based connectivity for reporting of test results directly from the jobsite. Compared to a standard test hammer, the Schmidt Live significantly increases productivity by eliminating the time required to record measurements and make calculations. Rebound value, number of impacts, impact angle, and series ID are automatically recorded and calculated. Data management and information sharing is enabled through the free Schmidt Live app for iOS and Android. Connecting to a web-based reporting tool via Bluetooth, the app allows real-time sharing of test data with off-site personnel. A logbook feature allows GPS positioning, notes, images, and audio comments to be added to the reports. The Live can also be used as a simple analog hammer.
