Load Ring and Gauge Blocks are each NIST Traceable and used together to verify applied loads and height measurements of Superpave Gyratory Compactors. The Load Ring and Gauge Blocks verify the calibration of the compactors in accordance with the test method and calibration schedule. The compactors should be verified semi-annually.
HMA-622 Load Ring has a 5,000lbf (22.2kN) load capacity and includes a dial gauge.
HMA-623 Gauge Blocks are 3x1in (76x25mm) WxH, constructed of hard steel, and individually serial-numbered. The Gauge Blocks Blocks are sold individually; verifying requires four.
Features:
- NIST Traceable Certification for both models
- Gauge blocks are serial-numbered
