The Penetrometer Apparatus is a precision laboratory instrument used to measure the consistency of lubricating greases and other semi-solid materials by determining penetration depth in DOP (Division of Penetrometer).
The test is conducted by allowing a standard cone or plunger to penetrate the sample under its own gravitational force for a specified time. The depth of penetration is directly indicated on a calibrated dial, providing accurate and repeatable results.
This penetrometer is widely used for testing lubricating greases, waxes, stiff paints, distempers, and soils, and is suitable for quality control laboratories, research institutes, and production units.
The instrument complies with major international and national test standards, ensuring global acceptance of test results.
