Feeler Gauge Set

HCM-CA0485, Feeler Gauge Set

A feeler gauge is a precision tool used for measuring the gap between two surfaces or the clearance between moving parts. It consists of a series of thin, flat metal blades of varying, precisely calibrated thicknesses, bound together at one end. Each blade is marked with its exact thickness.

Applications in Concrete Compression Testing

In the context of concrete compressive testing, a feeler gauge is an indispensable tool for ensuring the accuracy and reliability of test results. Its primary function is to verify the planeness and alignment of the testing machine's components, such as the base and platen.

• Precise Alignment: The gauge is used to check the gap between the base and platen, ensuring they are perfectly parallel. Proper alignment is crucial for applying a uniform compressive load to the concrete specimen, which is essential for obtaining accurate strength measurements.
• Quality Control: Feeler gauges are also used to measure mortar joint thickness, the width of cracks, and the flatness of concrete surfaces. These measurements are vital for assessing the structural integrity of buildings, bridges, and other infrastructure.
• Compliance: Using a calibrated feeler gauge helps testing laboratories adhere to industry standards like ASTM C39, which outlines the standard test method for compressive strength of cylindrical concrete specimens.

Features of Our Feeler Gauge Set

Our feeler gauges are designed for the demanding conditions of construction, civil engineering, and materials testing environments.

• High Accuracy: The blades are specially calibrated to ensure precise, reliable measurements, which are critical for determining the strength and quality of concrete.
• Durability: Made from high-quality stainless steel, the blades are corrosion-resistant and built to withstand contact with concrete mixtures and harsh job site conditions.
• Ease of Use: To use the gauge, simply insert the appropriate blade (or combination of blades) into the gap you wish to measure. The correct measurement is the thickness of the blade that fits snugly without being forced. This simple operation requires minimal training, making the feeler gauge a reliable and cost-effective tool for any technician.

A high-quality feeler gauge, used with a sturdy testing machine stand, improves the entire testing process by ensuring your equipment is correctly set up for accurate and repeatable results.
