product
DC Air Based Resistance
DC Air Based Resistance Standards are designed for high accuracy resistance calibration in air.
-
product
(DCC) Resistance Bridges
Direct Current Comparator (DCC) Resistance Bridges. Unique innovations in 6622A design and modularity means users no longer have to decide what Bridge satisfies current requirements as well as future requirements. Optional modules allow for normal, high ohms, and low ohms measurements without having to purchase multiple bridges as per competitive products.

DC Current Shunts
DC current shunts / standards are true 4-terminal devices that precisely measure DC currents from 10 A to 10,000 A. They use special alloys in the resistive elements which are supported on an insulating base for mechanical stability. The 9230A includes special features to reduce the effects of power dissipation and associated self heating errors. These shunts are designed to operate in air at full rated current. These are the best performing, and most widely used, DC metrology shunts in the world.

product
DC Precision Current Sources
DC Precision Current Sources provides precise and very stable output currents from 3 A to 10,000 A. The 6623A-PCS Series provides the best uncertainties of any DC high current sources (i.e. < 5 ppm of precision and stability at 1000A). In addition this Series is modular and initial output currents can be expanded at any time.

product
High Current DC Transformerd
High Current DC Transformer provides very accurate DC current measurements up to 3000 A with output current that varies directly with the input current in three ranges. This direct current transformer is designed with an open window to pass a single cable, set of cables, or buss bar that carry the direct current to be measured.
