Total stations are the primary survey instrument used in mining surveying. A total station is used to record the absolute location of the tunnel walls, ceilings (backs), and floors, as the drifts of an underground mine are driven.

The Deflection of Beam Apparatus is used to study the bending and deflection of beams under different loading conditions. It helps engineering students understand the relationship between load, span, material properties, and deflection (based on Euler–Bernoulli beam theory).

Civil lab equipment refers to the tools, instruments, and machines used in civil engineering laboratories to test, analyze, and study materials used in construction — such as cement, concrete, soil, bitumen, aggregates, and water.

These instruments help engineers, students, and researchers check the quality, strength, durability, and behavior of materials before using them in real construction projects.

The Abrasion Value Testing Apparatus is a precision-engineered instrument designed to determine the abrasion value of aggregates and materials, widely used in civil engineering and material science laboratories. This apparatus is ideal for educational institutions, research labs, and construction industries to evaluate the hardness and durability of materials. It is robust, easy to operate, and complies with standard testing protocols.

The Le Chatelier Mould is a special split brass mould used to determine the soundness of cement by the Le Chatelier test method. Soundness refers to the ability of cement to resist excessive expansion after setting, which is mainly caused by the presence of free lime or magnesia. Excessive expansion can lead to cracks and disintegration of concrete or mortar.

The mould is in the form of a cylindrical split ring with two indicator arms attached. When the cement paste is placed inside and allowed to set, any expansion pushes the arms apart. The increase in the distance between the tips of the arms indicates the unsoundness of cement.
