Techmaster provides ISO/IEC 17025:2017 accredited Time & Frequency calibration — accredited by ANAB (USA), traceable to the SI and recognized worldwide through ILAC-MRA. On-site service nationwide.
Time & frequency calibration determines the error of time and frequency instruments: frequency counters, stopwatches, timers and frequency standards. Techmaster’s ISO/IEC 17025:2017 lab is traceable to the SI second (s) and hertz (Hz).
Time and frequency are the most accurately realized quantities in metrology and underpin telecom, automation, testing and research. A drifting frequency reference affects every measurement that relies on it.
Techmaster calibrates time-frequency instruments against frequency references traceable to atomic standards (Cs/Rb) or GPS, ensuring traceability to the SI second and high accuracy.
The table below lists typical parameters & measurement ranges for this discipline.
| Parameter / Instrument | Typical measurement range | CMC / Measurement uncertainty |
|---|---|---|
| Frequency | 1 Hz – several GHz (instrument-dependent) | [Verify against scope] |
| Time interval | µs – hours | [Verify against scope] |
| Stopwatch | up to 24 h | [Verify against scope] |
| Stability | per reference standard | [Verify against scope] |
| Period | per instrument range | [Verify against scope] |
⚠ Note: The ranges & CMC below are typical reference values. Please verify against Techmaster’s official Scope of Accreditation before publishing — actual CMC depends on the reference standard, method and measurement conditions.
Time-frequency measurements are traceable to the SI second (s) and hertz (Hz) via a frequency reference traceable to Cs/Rb atomic standards or GPS signals synchronized to UTC.
Our lab is ISO/IEC 17025:2017 accredited by ANAB (USA); certificates are recognized worldwide through ILAC-MRA.
