Transfer Standards (AC/DC, Voltage)

Transfer standards are high‑stability reference instruments used to transfer measurement accuracy and traceability between calibration systems, laboratories, and locations. They are significant because they maintain predictable performance during transport, allowing calibration accuracy to be verified without moving sensitive primary standards.

Key applications include inter‑laboratory comparisons, verification of remote or on‑site calibration systems, ISO/IEC 17025 audits, and validation of third‑party calibration services. Transfer standards are commonly used for AC/DC voltage, current, resistance, and frequency comparisons. ATEC offers transfer standards from manufacturers such as Fluke Calibration, AMETEK, and Additel.
