UKAS PRT Calibration

UKAS Platinum Resistance Thermometer Calibration

We offer specialist PRT calibration both in house and on-site. 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 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 platinum resistance thermometer calibration however please speak to us if turnaround time is a concern.
