Environmental Chamber Calibration Services
The controller says 25.0 °C / 60 %RH. The product inside deserves a second opinion.
ACS Calibration delivers NIST-traceable, audit-ready environmental chamber calibration, available at the ACS central lab or directly on-site at facilities across the Southeast.
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.
What the Controller Doesn’t Know
An environmental chamber’s controller reports one point in a box full of gradients. Door seals age, circulation fans slow, heaters overshoot — and the samples sit wherever they sit, not where the control sensor does. Stability studies, battery testing, and conditioning protocols all assume the chamber is what its display claims.
We calibrate chamber indication and control against reference standards — temperature under our accredited capability and humidity — with as-found and as-left data. Thermocouple-based controllers are accredited when that simulation is on our current PJLA scope.
Chambers keep company: humidity chambers, stability chambers, ovens and incubators, and the loggers inside them all calibrate on one cycle — and onsite service means the chamber never leaves your floor.
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 Environmental Chamber Calibration
NIST-Traceable, Accredited on Request
Every calibration is NIST-traceable with real measurement data.
4–6 Business Day Typical Turnaround
