Our advanced laser-based calibration platform delivers exceptional dimensional accuracy while maintaining a >4:1 Test Uncertainty Ratio (TUR). Supported by NIST-traceable standards and performed under an ISO/IEC 17025-aligned quality system, we provide reliable, well-documented calibrations across a broad range of dimensional tools and reference artifacts, including:
Dimensional Standards & Reference Gages
Gage blocks (slip gages), setting standards, spheres, ring gages, cylindrical setting gages, segment gages, and CMM calibration tools (end standards, ball bars, setting masters)
Thread & Taper Measurement
NPT and pipe thread gages, API gages, tapered rings and plugs, threaded rings and plugs, variable screw thread gages (Tri-Roll), taps, dies, and select cutting tools
Precision Measuring Instruments
Micrometers (outside, inside, depth), dial indicators and test indicators, dial calipers, electronic/digital calipers, LVDTs, glass scales, snap gages, dial bore gages, swing gages, and steel rules
Specialized Components
Ball and rolling bearings (tapered, cylindrical, spherical, needle), shafts, gears, splines, pin and plug gages, feeler gages, coating thickness gage standards, and precision-machined parts
Your Complete Partner for Dimensional Calibration
When accuracy, traceability, and documentation matter, RPM delivers calibration you can stand behind.
