ASTM D1831 Lubricating Grease Roll Stability Tester

The KR-RST29 Grease Roll Stability Tester is applicable to the standard ASTM D1831, SH/T0122. When operating the instrument: use a certain amount of samples at room temperature and after working on the roller testing machine for 2 hours, measure the working penetration of the grease before and after the test. This instrument is suitable for measuring the consistency change of lubricating grease after working on the drum tester, to judge the mechanical shear stability of lubricating grease.
