pH Meter with ATC Calibration Services
Automatic temperature compensation only compensates correctly when the temperature is right.
ACS Calibration delivers NIST-traceable, audit-ready pH meter with ATC calibration, available at the ACS central lab or directly on-site at facilities across the Southeast. pH at the 4, 7, and 10 buffer points and conductivity from 100 µS/cm to 10 mS/cm are on our accredited scope, so ISO/IEC 17025 accredited certificates are available on request.
Analytical & Chemical Instruments We Calibrate
pH, conductivity, viscosity — plus the balances and pipettes on the same bench.
Frequently serviced brands: Oakton, Hanna Instruments, Mettler Toledo, Krohne, and Brookfield — plus dozens more.
Two Sensors, One Answer
ATC-equipped pH meters correct for temperature automatically — a genuine improvement with a hidden dependency. The compensation is only as good as the temperature probe feeding it, and a probe reading two degrees off skews every “compensated” pH value while looking like a feature working as designed.
We calibrate both halves of the system: pH response against certified reference materials at the accredited 4, 7, and 10 points, and the ATC temperature element against our accredited thermodynamic capability — with as-found and as-left data for each on the certificate.
Standard meters live on the pH meter page, conductivity meters get the same certified-reference treatment, and the lab’s thermometers and pipettes can join one audit-ready shipment.
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 pH Meter with ATC Calibration
NIST-Traceable, Accredited on Request
Every calibration is NIST-traceable with real measurement data. pH (4, 7, 10) and conductivity (100 µS/cm–10 mS/cm) 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.
