RPM Indicator Calibration Services

The panel says 1,750 rpm. The process is built on believing it.

ACS Calibration delivers NIST-traceable, audit-ready RPM indicator calibration, available at the ACS central lab or directly on-site at facilities across the Southeast. Frequency to 10 MHz, rotational speed to 99,900 rpm, and timers to 24 hours are on our accredited scope, so ISO/IEC 17025 accredited certificates are available on request.

Instrument Types

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.

Accredited Speed, Time & Frequency Capability

These ranges appear on our PJLA scope of accreditation — verify it independently anytime. From production tachometers to laboratory centrifuge RPM verification, instruments beyond these ranges receive NIST-traceable calibration.

Why It Matters

The Number the Operator Logs

Panel-mounted RPM indicators translate a sensor pulse into the number operators run the process by — agitator speed, line speed, pump RPM. Between the pickup, the signal conditioning, and the display, there’s plenty of room for the shown number and the shaft’s reality to drift apart, and the process log inherits whichever number the panel prefers.

We calibrate RPM indicators under our accredited rotational-speed scope — reference signals applied across the operating range, 60 to 18,000 rpm sourced and beyond verified by measurement to 99,900 rpm — with as-found and as-left data per point.

Indicators calibrate naturally alongside the handheld tachometers used to spot-check them and the speed indicators on neighboring lines — typically onsite, since panels don’t travel.

Deliverables

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
The ACS Difference

Why Companies Choose ACS for RPM Indicator Calibration

NIST-Traceable, Accredited on Request

Every calibration is NIST-traceable with real measurement data. Frequency (1 Hz–10 MHz), rotational speed (to 99,900 rpm), and timers/stopwatches (to 24 hours) are on our ISO/IEC 17025 accredited scope — accredited certificates available whenever your quality system requires them.

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.

How It Works

Calibration Without the Hassle

1. Ship It or Schedule Us

Send your instrument to our Dothan, AL laboratory — or book onsite service and we come to your facility.

2. NIST-Traceable Calibration

ASQ Certified Technicians calibrate your instrument against NIST-traceable reference standards — in our lab or at your facility.

3. Audit-Ready Certificate

Your instrument returns with a NIST-traceable certificate documenting as-found and as-left data. ISO/IEC 17025 accredited certificates available on request.
