Rex OS-AUTO Motorized Durometer Test Stand

Durometer Sold Separately

---

The Rex OS-AUTO Motorized Durometer Test Stand provides constant load, controlled rate of descent, and application velocity, through a geared electric motor and braking mechanism that alternately lowers the durometer onto the specimen and then raises it in preparation for the next test.

This Rex OS-AUTO also provides an electronic timer that can adjust the amount of time the durometer remains in the lowered position (dwell time).

The durometer and carriage assembly have a mass sufficient for use with Types A, B and O. The incorporation of the large detachable mass is required for testing with Type C, D and DO durometers. This detachable mass can be purchased separately. The OS-AUTO can also be configured for use with durometer Types OO, OOO and OOO-S.

Adjustment of the durometer for specimen thickness is easily accomplished by a height adjusting knob on the top of the stand.
