ASTM D4289 Compatibility of Synthetic 

Rubber and Grease Tester

Mode:JF0436

Product introduction: 

This instrument is suitable for determining the compatibility of lubricating grease with standard synthetic rubber. Place a standard synthetic rubber test piece with a specified size in a grease sample at a certain temperature, and use its volume change and hardness change to evaluate the compatibility of the grease with the standard synthetic rubber after a 70-hour test.

Features

◆Standard chloroprene rubber and nitrile rubber test piece: 50×25×2mm;

◆Microcomputer temperature controller, digital display, accuracy ±1℃, PT100 sensor;

◆The heating box has a transparent observation window, which is convenient for operation and observation;

◆Digital display timer, record test time, with time alarm;
