Continual investment in calibration systems and equipment to retain Sira's strong position as a provider of process-related calibration services
Sira Test and Certification announces further levels of automation in its temperature calibration laboratory at its Chislehurst headquarters.
These increased levels of automation, along with a recent expansion in the range of calibration baths, has led to an improved throughput capability and hence faster turnaround times - even for work received on an ad-hoc basis.
For customers requiring very rapid turnaround times Sira also offers an advanced booking service.
Sira has continued to develop its in-house software to monitor calibration bath gradients and fluctuations as well as establishing the point at which satisfactory equilibration of the instrument under test has occurred.
Like all other Sira calibration offerings, temperature measurement services are Ukas accredited and cover a broad range of electrical and mechanical instrumentation, including platinum resistance and liquid-in-glass thermometers, thermocouples and thermocouple systems, temperature indicators and dry block calibrators.
Each instrument calibrated by the laboratory receives the Ukas certificate stating the ITS-90 temperature, as well as the instrument indication (or output) and the appropriate measurement uncertainties.
The laboratory covers temperature calibration in the range -80C to 1300C.
Uncertainties vary depending on the instrument under calibration, the method used and the calibration temperature.
Typically for the best equipment, the uncertainty will be 0.05C.
However, values can be as low as 0.012C at the triple point of water and will exceed 2C for thermocouples at 1300C.
