Why ACS

About ACS Calibration Services

NIST-traceable, professional calibration

Our technicians use certified, NIST-traceable calibration equipment to verify accuracy and adjust your instruments as needed—maintaining consistent and dependable performance.

Comprehensive calibration for key instruments

We calibrate the sensors and transmitters your system relies on every day, including:

  • Pressure transducers

  • Flow meters

  • Level transmitters

  • pH & ORP sensors

  • Dissolved oxygen sensors

  • Chlorine analyzers

  • Turbidity instruments

  • Temperature sensors

  • Chemical feed monitoring devices

Detailed calibration reports for compliance

Each calibration includes a written report showing “as found” and “as left” values, adjustments made, and any equipment issues—supporting regulatory and audit requirements.

Troubleshooting & performance verification

If a sensor is drifting, unresponsive, or out of range, we diagnose the issue and correct it—or recommend replacement if calibration cannot restore accuracy.

Recurring & annual calibration options

ACS offers scheduled calibration programs to keep your instruments reliable year-round and ensure compliance with state and federal water quality standards.
