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.
