Direct Current Comparator Bridge 6622A

• Widest Available Range from 1 mΩ ~1 GΩ
• Best Accuracy: ± 0.015 ppm of Reading
• Internal Voltages up to 1000 Vdc
• Extended Low End Range Down to 1 μΩ with Currents Up to 10,000 A
• Change All Key Parameters “IN-REAL-TIME” While the Measurement is Running

• Guildline Instruments 6622A Series has unique technology and provides the best in measurement uncertainties for Direct Current Comparator (DCC) Resistance Bridges manufactured by anyone today. The 6622A is the most widely deployed Resistance Bridge in the world with over 200 Bridges in use today at NMIs, militaries and calibration laboratories. Unique innovations in design and modularity means users no longer have to decide what Bridge satisfies current requirements as well as guess as to what Bridge would meet future requirements. Optional modules allow for normal, high ohms, and low ohms measurements without having to purchase multiple bridges.
