Relative Humidity Sensor Calibration Services
The wall-mounted sensor nobody touches is quietly deciding compliance every minute.
ACS Calibration delivers NIST-traceable, audit-ready relative humidity sensor 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.
Fixed Sensors, Drifting Truth
RH transmitters bolted to walls and ducts feed building automation, cleanroom monitoring, and chamber control loops — and precisely because they’re installed and forgotten, their drift goes unchallenged. A capacitive element that’s aged a few percent doesn’t alarm; it just moves the whole room’s recorded history.
We calibrate RH sensors and transmitters against humidity references, verifying the sensor and its output signal, with as-found and as-left data that tells you exactly what the building system has been logging. Temperature elements in combined sensors are covered under the same accredited scope.
In-place calibration via onsite service keeps control loops live; swap-and-rotate programs work too. Pair with the loggers validating the same spaces and the chambers those sensors steer.
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 RH Sensor Calibration
