UKAS Humidity Calibration Services
Choose Withnell Sensors for Your Humidity Calibration
UKAS-accredited humidity calibration is the most reliable way to ensure that your humidity monitoring equipment is performing as specified.
Many regulated industries including pharmaceutical, medical, laboratory and healthcare organisations rely on accredited humidity calibration to support compliance and quality assurance programmes.
Our UKAS-accredited services and ISO-accredited facilities demonstrate our competence and commitment to delivering accurate, traceable calibration results.


UKAS Accreditation
We operate a UKAS-accredited calibration laboratory, providing independently assessed humidity calibration services you can rely on. Our accreditation demonstrates that our laboratory, methods and quality processes meet recognised standards for technical competence and measurement traceability.
This gives you confidence that your sensors have been calibrated accurately, with clear and auditable documentation. It also helps organisations working in regulated and quality-controlled environments demonstrate compliance, maintain reliable records and prepare for audits.
Why Do We Calibrate Humidity Sensors?
Humidity calibration is an essential process for validating the accuracy and efficiency of humidity monitoring equipment.
Calibrated humidity monitoring devices help deliver precise humidity readings across a wide range of applications. Industries such as food production, pharmaceuticals and chemicals depend on accurate humidity measurements to prevent condensation, corrosion, mould growth and product spoilage.
Humidity is a highly controlled environmental parameter and can impact product quality, regulatory compliance and operational performance.

Humidity Calibration Capabilities
Whether you are using your equipment for routine monitoring of your cold chain or validating humidity deviations during a critical process, we can support both routine and ad-hoc humidity calibration requirements.
We provide UKAS humidity calibration for a wide range of data loggers and sensors from manufacturers including SenseAnywhere, Vaisala, LogTag, Elitech, Testo, Comark, ETI, TinyTag, Hanwell, Omega and Fluke.
Using our Thunder Scientific humidity chamber, we can offer highly accurate humidity calibrations with low measurement uncertainties.
Our capabilities include:
Humidity calibration from
10%RH to 90%RH
Temperature calibration from
10°C to 60°C
