Transmille offer 17025 Accredited DC Current calibration services from ± 0nA to ± 100A using a variety of techniques depending upon the uncertainty required

From Picoamps to Kiloamps

Our laboratory uses precision techniques applicable to the type of work being performed.

Measurement of currents is performed through current shunts and resistors depending upon the magnitude of current being generated. For currents below 100uA, precision voltages are sourced across high value resistors. For higher currents, current shunts and current amplifiers are used.

For currents above 100A, currents are generated using an EA002 and a multiproduct calibrator to generate up to 1500A
