W.S. Tyler
RO-TAP® RX-29
The gold standard in test sieve shakers, W.S. Tyler RO-TAP® RX-29 utilizes a unique two-dimensional operation: a horizontal, circular, and vertical tapping motion. This dual action allows particles to stratify and “seek” critical openings in the test media.
In turn, the most accurate and consistent particle analysis testing is achieved with minimal maintenance.
The W.S. Tyler RO-TAP RX-29 is designed for use with 8-inch diameter W.S. Tyler test sieves.
Each unit is tested and serialized before shipment. It features a 99-minute digital timer/clock with a tolerance of .1 seconds.
- Requires minimal maintenance
- Heavy-duty use
- Features 99-minute digital timer/clock, tolerance, 0.1 second
- Each unit is test run and serialized prior to shipment
