Grease Penetrometer ASTM S217

A Grease Penetrometer ASTM S217 measures the consistency of lubricating grease by determining how far a standard cone penetrates the grease under controlled conditions.

Grease Penetrometer ASTM S217

Compliance Standard : ASTM D217 – Standard Test Methods for Cone Penetration of Lubricating Grease,  IP 50 – Cone Penetration of Lubricating Grease,  ISO 2137 – Petroleum products – Lubricating grease – Determination of cone penetration
Application : The Grease Penetrometer is used for the determination of cone penetration of lubricating greases, which is a direct measure of grease consistency and NLGI grade. It is an essential instrument in petroleum laboratories, grease manufacturing units, lubricant quality control labs, R&D centers, and inspection agencies.

Applications include:

  • Determination of worked and unworked penetration of greases

  • Quality control and grading of lubricating greases

  • Evaluation of grease consistency changes after working

Product Description :  The apparatus consists of a rigid vertical stand, precision dial gauge, cone release mechanism, and sample platform. The design ensures smooth cone release, accurate vertical alignment, and repeatable results.
The instrument is suitable for unworked, worked (60 strokes), and prolonged worked penetration tests as specified in ASTM D217.
