PRS
Model: PRS / PRS-S
High-speed automatic Rockwell tester designed for integration into production lines and 100% testing, particularly of bearings.
About the PRS
Complete automatic hardness test cycle including the clamping of the piece, application of the load, hardness measurement, release of the piece, return to starting point and it is ready for a new test. High volume measurements, the tester can easily be introduced into the conveyor lines, yielding up to 1500 test per hour.
Direct readout in Rockwell or Brinell scales with electronic data output and automatic sorting of the results by low, ok, or high hardness levels depending upon the preset tolerances.

How the PRS works
High Speed Rockwell Hardness Tester
High speed automatic hardness tester integrable in production lines. Especially suitable for Rockwell hardness tests on bearings.
Rockwell and superficial Rockwell ISO 6508 / ASTM E-18
HRA – HRB – HRC – HRD – HRF – HRG – HRL – HRM – HRR / HRN – HRT
Brinell HBWT ASTM E-103 / SO 6506
1/30 – 1/10 – 2.5/15.6 – 2.5/31.5 – 2.5/62.5 – 2.5/187.5 – 5/125
100% Production Test
Direct readout in Rockwell or Brinell scales with electronic data output and automatic sorting of the results by low, ok, or high hardness levels depending upon the preset tolerances.
- Pneumatic high-speed Rockwell hardness tester
- High volume tests, up to 1500 tests per hour
- Fully automatic hardness tests
- Very easy integration in conveyor lines
- Can work 24/24 hours, 7/7 days
- Light lamp for direct sample approval relatively to tolerance
- Automatic clamping system active for unstable test sample
- Auto-compensation system to avoid measurement errors on oiled and dirty samples
