Guildline Instruments 9230A series of precision DC current shunts are true 4-terminal devices intended for the ultra-precise measurement of DC current. They are constructed from specially selected elements supported on an insulating base for mechanical stability. These units are covered with a perforated metal shell to allow proper cooling while providing physical protection of the elements. Available Forced Convection option allows improved thermal dissipation and higher current measurements. Models are available for current measurement ranges from 5A up to 12,000 A with custom ranges available. The optional forced air attachment extends the measurement range of the unit by a factor of two.

Guildline Instruments 9340 series of precision DC Resistance Standards are a complete family of easy to use resistance standards offering the best combination of highest accuracy and widest range commercially available. There are 5 standard types available from 3 dial to 7 dial. The smallest increment offered is 10 mΩ full-scale total resistance available is just over 10 TΩ full-scale resistance values in the range are available in all the dial sizes. Accuracy of the 9340 Decade Resistance Boxes is better than ± 0.01% from mid range of 1Ω to 10MΩ steps. This means Guildline decade boxes are over 20 times more accurate than most competitors’ floor specifications.
