Platinum Resistance Thermometer Calibration Services
The reference class — RTDs and PRTs are what other thermometers get checked against.
ACS Calibration delivers NIST-traceable, audit-ready platinum resistance thermometer calibration, available at the ACS central lab or directly on-site at facilities across the Southeast. Temperature from -196 °C to 420 °C, infrared to 500 °C, and humidity from 30 to 75 %RH are on our accredited scope, so ISO/IEC 17025 accredited certificates are available on request.
Temperature & Humidity Instruments We Calibrate
From cryogenic checks to furnace controllers — if it reads degrees or percent RH, we can almost certainly handle it.
Frequently serviced brands: Traceable (Control Company), Gemini Tinytag, T&D, MadgeTech, Fluke, ThermoWorks, LogTag, and ThermoPro — plus dozens more.
When the Standard Itself Needs a Standard
Platinum resistance thermometers hold the top of the accuracy pyramid in most facilities: the reference the process probes get compared to, the sensor in the critical vessel, the element inside the dry well. That status cuts both ways — a drifted PRT doesn’t just miss, it quietly re-baselines everything checked against it. And platinum’s enemy is mechanical shock: one dropped case can shift a PRT more than a year of use.
We calibrate PRTs and RTDs by comparison against reference standards from -196 to 420 °C under our accredited capability — standalone or as a system with your readout — with as-found and as-left resistance and temperature data documented.
Everything downstream of the reference belongs on the same cycle: digital thermometers, data loggers, and the chambers the probes monitor — one shipment, one traceability chain.
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 PRT & RTD Calibration
NIST-Traceable, Accredited on Request
Every calibration is NIST-traceable with real measurement data. Temperature (-196 to 420 °C), infrared (35–500 °C), and humidity (30–75 %RH) 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.
