UKAS Chamber Calibration
Chamber calibration services are essential for maintaining confidence in temperature-controlled environments used for pharmaceutical products, biologics, vaccines, laboratory samples and other temperature-sensitive materials.
Temperature drift within fridges, freezers and cold storage environments can lead to compliance risks, product loss and inconsistent storage conditions. Our UKAS-accredited fridge calibration and freezer calibration services help organisations maintain temperature accuracy, traceability and audit readiness.

Why is Chamber Calibration Important?
Chamber calibration helps verify that temperature-controlled equipment is operating within defined tolerances and maintaining stable storage conditions across the required temperature range.
Chamber calibration services are commonly required within:
Pharmaceutical and biotech storage
Healthcare and vaccine
storage
Laboratory and research environments
Controlled storage and cold rooms
Manufacturing and production facilities
Laboratory & Biotech Fridge and Freezer Calibration
We support laboratories, pharmaceutical organisations and biotech facilities with freezer calibration services for a wide range of temperature-controlled storage equipment, including:
- Laboratory fridges and freezers
- Ultra-low temperature (ULT) freezers
- Blood bank and vaccine fridges
- Sample and repository storage freezers
- Controlled storage units
Our engineers understand the operational and compliance requirements associated with regulated storage environments and can support both routine and specialist calibration requirements.


Cold Room Calibration
In addition to fridge and freezer calibration services, we also provide calibration support for:
- Cold rooms and walk-in storage environments
- Stability chambers
- Environmental chambers
- Temperature-controlled storage areas
These services help verify environmental consistency across larger storage and testing environments where temperature stability is critical to product quality and compliance.
Onsite Calibration Services
We provide onsite fridge and freezer calibration services across the UK to minimise disruption and reduce downtime within operational environments.
Using calibrated reference equipment and traceable processes, our engineers can carry out calibration services directly within laboratories, healthcare facilities, manufacturing sites and controlled storage environments.


The withnell way
Why Withnell Sensors?
At Withnell Sensors, we maintain numerous calibration baths and chambers to offer specific temperature points to suit your needs.
We conduct thousands of UKAS-accredited temperature calibrations every year. Our extensive range of equipment and high precision laboratory in Lancashire, enables us to offer fixed point and comparison temperature calibrations across the range of -196 to 420°C.
Withnell Sensors prides itself on offering some of the best measurement uncertainties in the UK. From this, our portfolio of temperature calibration services has evolved into specific niche requirements. We also offer rental services for a range of equipment to cover downtime during your calibration.
