Resistance Calibration

Absolute Calibration offers some of the best resistance Calibration and Measurement Capabilities outside of the National Physical Laboratory, making it the best independent laboratory for UKAS resistance calibration in the UK. Many calibration laboratories in the UK use Absolute Calibration for the UKAS Calibration of their standard resistors as Absolute Calibration offer the required uncertainties, a quick turnaround and a price a quarter of the National Physical Laboratory (NPL). Our DC resistance calibration measurement is by Direct Current Comparison (DCC) using the state-of-the-art Guildline 6625 Resistance Measurement System (incorporating a Guildline 6622A Bridge) from 1 m? to 1 G? achieving UKAS resistance calibration uncertainties from 0.07 ppm and at currents up to 150 A utilising the Guildline 6623A Range Extender. Measurement and sourcing of AC resistance calibration from 40 Hz up to 1592 Hz from 0.1 to 10 kohm result in uncertainties from 6 ppm to 0.030%. Low Value Resistors Absolute Calibration's UKAS resistance Calibration and Measurement Capability is for 4-terminal resistors suitable for oil immersion at 20°C. The uncertainties may be increased for other types of resistors.
