GMW offers AC and DC current calibration services for Current Transducers. The lab employs high precision calibration techniques that allow calibration uncertainties below 50PPM for DC primary currents up to 16kA. 0 to 400Hz AC current calibrations are available with uncertainties below 0.1% with primary currents up to 16kA peak. All current calibrations come standard with before and after 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.
