UKAS Temperature Calibration

Why use UKAS Temperature Calibration Services

UKAS Temperature Calibration is required for many industries to validate the accuracy and efficiency of temperature monitoring equipment. Temperature is one of the most monitored and controlled parameters in industry today. Temperature fluctuations can have an impact on personal comfort, product quality, regulatory compliance, and safety. Increasingly, we are also seeing many businesses controlling workplace conditions from an environmental perspective. Unnecessary and inefficient heating/cooling of spaces can have a negative impact on climate change. Accurate, calibrated temperature monitoring devices and thermometers are essential across a diverse range of applications and industries. UKAS accredited ISO 17025:2017 temperature calibration is the most reliable way to ensure that your equipment is performing as per your specified requirements. Many regulated industries including pharmaceutical, medical laboratories and healthcare now insist on an accredited calibration as a way of delivering complete quality assurance. UKAS audit our facilities, competency and processes every year to ensure we deliver consistently against the standards of ISO 17025:2017. This is one of the many reasons why an accredited calibration should be your choice of service, read more on this topic in our blog post here.

Our UKAS Temperature Calibration

Whether you are using your equipment for routine monitoring of your cold chain or for validating temperature deviations during a critical process, we can help to cover your annual temperature calibration. Our experienced team of calibration engineers can process equipment from any number of manufacturers including SenseAnywhere, Vaisala, LogTag, Elitech, Testo, Comark, ETI, TinyTag, Elitech, Hanwell, Omega, Fluke and many others.

We conduct thousands of UKAS accredited temperature calibrations every year including maintaining our own comprehensive range of temperature data loggers. We have an extensive range of equipment in our high precision laboratory in Lancashire. This enables us to offer fixed point and comparison calibrations across the range of -196 to 420°C offering some of the best measurement uncertainties in the UK. We maintain many calibration baths and temperature chambers meaning we can offer specific temperature points to suit your needs. Please download our schedule of accreditation or message one of our technicians with your requirements.


Years Accredited

Since early 2011 we have been proud of our UKAS temperature calibration accreditation.

Annual Calibrations

Thousands of calibrations completed each year with additional capacity to see this figure grow.


Temperature, Voltage & Humidity. Offering some of the best measurement uncertainties in the UK.

Brands Calibrated

And counting! We can calibrate most temperature data loggers and probes.

UKAS Data Logger Calibration

We offer UKAS calibration for a range of data loggers with temperature points covered from -90 to 250°C. Our UKAS data logger calibration service is tailored to your requirements, the number of calibration points and required temperatures can be modified to suit your needs. We will always strive to meet the required turnaround times as we understand the inconvenience of having equipment away for calibration. We offer a rental service on a range of loggers to support your needs while equipment is being calibrated. Our lab is equipped with extensive equipment to allow us to complete large numbers of calibrations at any one point which allows us to offer a competitive pricing structure on multiple loggers. At Withnell Sensors cost efficiency doesn't need to mean a compromise in quality or accuracy.

UKAS Accredited Kaye Calibration

Very few service providers have the capability to support and adjust this equipment, our engineers have many years of experience calibrating and servicing the Kaye equipment. Our Kaye calibration method simulates that recommended by the manufacturer, a method which we feel best suits the instruments to deliver optimal performance. We are currently the only service provider in Europe capable of offering a 17025 accredited calibration of the Kaye Validator system. Our own Kaye equipment is calibrated annually in line with manufacturer recommendations and the standard service for this equipment involves the collection of 'As Found' data, a full calibration and adjustment followed by an 'As Left' verification. We are also an authorised partner for Kaye within the UK and Ireland with exclusive training in the calibration of Kaye technology. We have most recently become UKAS accredited for the calibration of the all new Kaye Advanced Validation System (AVS) which has become the gold standard for thermal validation. We are the first laboratory to be able to offer UKAS calibration on the AVS in the United Kingdom & Ireland.

UKAS Temperature Block Calibration

Temperature reference blocks are used across a wide variety of industries most predominantly to provide temperature verification of thermocouples, data loggers and temperature sensors.

Temperature block calibration should be performed periodically to ensure that your equipment is displaying accurate information and functioning in line with specification. A calibration provides assurances of the accuracy of the display and delivers information on the temperature distribution and uniformity of the block. An accredited calibration of your temperature block will provide assurance that your calibration system, as a whole, is accurate and reliable.

Our experienced technicians have worked with temperature blocks from leading brands including Ametek, Druck, Fluke and Kaye. Strenuous testing is completed during the calibration to demonstrate how the temperature can differ from the cross section, as well as any temperature variances along the borings.We would love to discuss your next temperature block calibration, speak to us and benefit from the additional reassurances that only a UKAS accredited calibration can provide.

UKAS PRT Temperature Calibration

Medium to high accuracy PRT's form an integral part of many calibration systems used across a wide range of industries and applications. In order to provide traceability, prevent drift and to ensure that your own results are accurate, regular calibration of your temperature standard is recommended. Accuracy of calibration is often critical as the measurement uncertainties that we provide will have an impact on your own calibration accuracy. We use a combination of fixed points and fluid comparison baths to offer precision PRT temperature calibration from -196 to 420°C. Our service is always tailored to your requirements, the number of calibration points and required temperatures can be modified to suit your needs. Our continuous investment in laboratory equipment ensures that we have the capacity to cater for customers with a range of requirements. We understand the inconvenience of having equipment away for calibration therefore our lab team strive to protect the best possible turn around times for PRT temperature calibration however please speak to us if turnaround time is a concern.


UKAS Chamber, Fridge & Freezer Calibration

Withnell Sensors can provide UKAS accredited calibration of temperature controlled enclosures, such as, chambers, fridges and freezer calibration. Calibration of a temperature controlled enclosure, to put simply, is the process of identifying the difference between the displayed values of the enclosure and the corresponding values measured within the enclosure through external measurement equipment. The external equipment itself will have been checked against a known and verified source to establish accuracy. A UKAS calibration provides the added reassurance in the validity of the results due to the transparency and methodology used in the process.


UKAS On Site Probe Calibration

We offer on site UKAS (or traceable) calibration for a range of data loggers and probes with temperature points covered from -90 to 140°C. Our on site UKAS data logger calibration service is tailored to your requirements, the number of calibration points and required temperatures can be modified to suit your needs. Our expert service engineers will travel anywhere in the UK & Ireland- utilising our top quality calibration equipment to complete calibrations without your kit having to leave the building.
