AC & DC Current Transducer Calibration

Your ability to deliver accurate and reliable measurements depends on the stability of your equipment, and your equipment depends on the accuracy and quality of its calibration. With over 25 years of calibration experience, GMW offers AC and DC Standard or Accredited current calibration services for Current Transducers at our San Carlos, CA location and On-Site for minimal disruption of daily operations. The lab employs high precision calibration techniques that allow calibration uncertainties to 50PPM for DC primary currents up to 16kA and uncertainties to 0.1% for primary currents at 0 to 400Hz up to 16kA peak. All current calibrations come standard with data as well as statements about total uncertainty. Most of our lab’s calibration standards are directly traceable to NIST and NRC. Available are standard calibration options for single or multi-channel transducers systems and transducer heads. For custom calibration requests contact GMW. Delivery is typically 10 business days after receipt. GMW’s lab also has the ability to do in-house repairs as required.

GMW distributes current measuring devices from manufactures such Bergoz, PEM, Magnelab and also brokers current calibrations for the these current measuring devices back to the manufacture. Delivery is typically 30 business days after receipt.
