ValiDator® I & II

Category:

Nuclear Gauge Calibration and Verification System

ASTM standard for gauges and block calibrations – ASTM D7759
AASHTO T310 (verification)

The ValiDator is patented, NIST traceable, & ISO/IEC 17025 Accredited technology that can verify your nuclear density gauge calibration at all measurement depths.

Others have tried, but InstroTek is the only company with the know how and the technology to develop this innovative device.

ASTM & AASHTO standards for calibration and verification of gauges via blocks and ValiDator:

  • ASTM standard for gauges and block calibrations – ASTM D7759
  • AASHTO standard for gauges – AASHTO T310 (verification)

Per the ASTM D7759 standard, gauges can be calibrated and verified by the ValiDator and should be done so every 12 months. Per AASHTO T310, gauges can be verified with the ValiDator within 12 months of being calibrated via “multi-block” calibration. From T310: “If the verification process indicates a variance beyond the specified tolerances, the gauge shall be calibrated.”
