Proving Rings are used for load measurements and are used in the outfit a number of soil/cement & Bitumen. Testing Equipment's like Direct shear test apparatus, triaxial shear test apparatus, C.B.R. Test, Unconfined Test, Marshall Test etc.

They are made out of special steel careful forged to give maximum strength and machined to give highest sensitivity combined is measured by a sensitive dial gauge fixed co-axially at the centre of the proving ring.

The dial gauge readings thus obtained versus load applied enable the operator to Findus unknown load, just by noting the dial gauge reading for the unknown load. The proving Rings have high elasticity and on removing load they regain their original shape provided they are loaded in their elastic limits.

Calibration charts from standard Laboratories for the Proving Rings ordered are also available at extra cost. All proving rings are Integral Type. Integral type compressive Proving Rings of different capacities form 50kgf to 200000 kgf ar available.
