Product Code: C018
Category: CEMENT
Sub-Category: PHYSICAL PROPERTIES
- The Length Comparator is a precision instrument designed to measure length changes in hardened cement paste, mortar, and concrete prisms, essential for assessing dimensional stability and potential expansion or shrinkage.
- Equipped with a high-resolution gauge (12.7 mm travel), it ensures accurate and repeatable measurements, facilitating compliance with stringent testing standards.
- The apparatus features a sturdy two-column steel frame with an adjustable top anvil, accommodating specimens of varying lengths up to 300 mm, enhancing versatility in testing applications.
- A reference bar is utilized for calibration, providing a stable baseline for precise length change measurements over time.
- The comparator is compatible with various specimen sizes and configurations, aligning with international standards for evaluating the dimensional stability of cementitious materials.
- Reference Rods should be ordered separately.
