The HRB 754 Ring & Ball Tester automatically determines the softening point of bitumen, tar, pitch, tall oil rosins, and polymeric resins via standard ring and ball test methods.

In addition to performing standard softening point tests, this versatile analyzer is easily programmed with your own customized test protocols.

The HRB 754 incorporates laser light and photo-transistor detection for ultra precise recognition of softening point. Smart software distinguishes between air bubbles and the falling balls. Plus, a multi-point calibration table ensures precision across a wide bath temperature testing range.
