Frequency Counter Calibration Services
The bench reference for everything periodic.
ACS Calibration delivers NIST-traceable, audit-ready frequency counter calibration, available at the ACS central lab or directly on-site at facilities across the Southeast.
Speed, Time & Frequency Instruments We Calibrate
RPM, hertz, and seconds — from plant-floor tachometers to laboratory centrifuges.
Frequently serviced brands: Traceable (Control Company), Shimpo, Extech, Eppendorf, Thermo Fisher Scientific, and Micron — plus dozens more.
Counting on the Counter
Frequency counters are quiet references: verifying oscillator outputs, checking signal generators, troubleshooting control signals, timing events everything else on the bench gets compared against. Their internal timebase is the whole instrument — and timebases age, a few parts per million a year, in a straight line that never announces itself.
We calibrate frequency counters under our accredited scope — measurement verified from 1 Hz to 10 MHz against reference frequency standards, with as-found and as-left data that quantifies exactly how far the timebase has walked since last cycle.
Counters share benches with multimeters and calibrators — all covered under our accredited electrical and frequency scope, all one shipment. Tachometers reading frequency-derived RPM ride along too.
What You Get With Every Calibration
- NIST-traceable calibration certificate with real measurement data — not just a pass/fail sticker
- As-found and as-left readings, so drift is documented
- ISO/IEC 17025 accredited certificate with reported uncertainty — on request
- Calibration label with due date, plus a reminder before your next calibration is due
Why Companies Choose ACS for Frequency Counter Calibration
NIST-Traceable, Accredited on Request
Every calibration is NIST-traceable with real measurement data.
4–6 Business Day Typical Turnaround
Keep production moving. Most instruments are typically completed in 4 to 6 business days from arrival, with rush options available when a line is down.
Flexible Logistics
Mail your instruments in, or schedule onsite calibration and we come to your floor — serving Alabama, Florida, Georgia, Mississippi, Tennessee, South Carolina, and beyond.
