Stainless Steel Length Comparator, Power Source : Electric

The Length Comparator is a precision-engineered instrument designed for measuring the dimensional changes in materials such as cement, concrete, and metals. It is commonly used to determine the drying shrinkage, swelling, or expansion of test specimens over time.

Built with a solid cast iron or mild steel frame, the comparator ensures rigidity and vibration-free operation, enabling repeatable and accurate readings. The instrument is fitted with a high-resolution dial gauge having a least count of 0.001 mm or 0.01 mm, allowing users to detect even the slightest variations in specimen length.

The specimen is placed between two accurately machined reference points—one fixed and one movable—connected to the dial gauge for direct reading of the change in length. Its robust and corrosion-resistant construction ensures durability and long service life in laboratory environments.

The V-Tech Length Comparator complies with international and Indian standards for material testing and is suitable for use in both educational and industrial laboratories.
