Nunes Instruments - Soil Testing Equipment

Soft and Sensitive soils whose shear strength is less than 15 KN/m2, the results are dependent on operator’s skill, Even Pushing the sample tubes in soil may cause some disturbance. Experience shows that carefully controlled compression test results can be related to figures obtained by pushing a small vane in the soil and rotating it at a acontrolled rate and measuring the force, required for maximum resistance. Vane Shear Test can be conducted in a laboratory or in the field.

Types & Specfications

vane Shear Appartus Hand Operated

It Consists of a torque head adjustable in height by means of a lead screw rotated by a drive wheel to enable the vane to be lowered into the specimen Rotation of the vane is by means of a hand wheel which operates a worm gear arrangement turning the upper end of a calibrated torsion spring Vane dia, rod dia, vane size & vane height are as per is specifications The Vane shaft is attached through the hollow upper shaft to a re-settable pointer, which indicates the angle of torque on a dial graduated in degrees The dial reading multiplied by spring factor gives the torque A Container for soil sample is also supplied, and a sampling tube of 38mm I.D & 150mm long can also be used as container Supplied with set of four springs, one each of approx. 2 Kg cm, 4kg cm and 8kg cm Complete as above in a wooden carrying case.

The Motorized Load Frame is a robust and precision-engineered testing apparatus designed for performing California Bearing Ratio (CBR) and Triaxial Shear Tests on soil specimens. It determines the bearing capacity and shear strength of soilessential parameters in the design of flexible pavements, embankments, and foundations.
The unit features a 50 kN motorized loading frame with a constant strain rate drive mechanism, ensuring accurate, uniform load application. It can be equipped with a proving ring and dial gauge for manual testing or upgraded with digital load and displacement indicators for data precision.

• Heavy-duty 50 kN motorized loading frame for accurate testing.

• Suitable for CBR, Triaxial, and Unconfined Compression tests.

• Constant strain rate motor ensures smooth and precise loading.

• Variable speed control to accommodate different test types.

• Sturdy two-pillar design for maximum stability.

• Available in manual and digital configurations.

• Built to meet standard testing specifications (IS: 2720, ASTM D1883).

• Civil engineering and geotechnical laboratories for soil testing.

• Highway and pavement design for determining subgrade bearing capacity.

• Foundation design and soil strength evaluation.

• Research and academic laboratories for soil mechanics studies.

A Universal Load Frame is a versatile and robust testing machine used for performing a wide range of mechanical tests on materials, such as tensile, compression, and flexural tests. It is designed to apply precise loads to specimens and measure their mechanical properties, including strength, elasticity, and deformation under different stress conditions. Universal load frames are commonly employed in materials testing, quality control, research and development, and compliance with industry standards.

Key Features:

Multi-Functionality: Capable of performing various tests, including tensile, compression, bending, shear, and fatigue tests on different materials (metals, polymers, ceramics, composites, etc.).

High Precision: Equipped with advanced load cells, displacement sensors, and extensometers, offering accurate force measurements and displacement control during tests.

Wide Load Capacity: Available in different load ranges to suit various testing needs, from small-scale materials testing to high-force applications.

Adjustable Crosshead: The crosshead can be easily adjusted for different test specimen sizes, ensuring versatility in testing a wide range of materials.

Lightweight and portable, this Soil Test Direct Soil EC Tester directly measures soil conductivity and temperature. Our Soil Test Direct Soil EC Tester has a penetration probe that features a built-in temperature sensor, allowing for measurements that are automatically temperature compensated. The conductivity range can be calibrated at one point, and tester calibration is done in a standardized solution. We offer 4.5 penetration conductivity probe, calibration screwdriver, batteries, and instruction manual along with this Soil Test Direct Soil EC Tester.
