6625A Series of Resistance and Current Measurement Systems Consider Guildline’s 6622A Series of Modular and Upgradeable DCC Bridges, specifically the 6622A-Base Model (shown right). This model goes from 1 mΩ to 100 kΩ and at measurement uncertainties staring at 0.1 ppm with currents at 150 mA. Now you want to increase your upper measurement range to 1 GΩ and voltages to 1000 V. You simply Base Model return the bridge to Guildline. We add internal board upgrades to the same unit that you returned, calibrate the Bridge, and return this same Bridge back to you. It will fit exactly where it fit before,...

6625A Series of Resistance and Current Measurement Systems The 6622A Series Bridge provides a full 10.5 digits of resolution and the ability to graphically see the data (trending). You can have the data presented in a summary or detailed format right on the Bridge Screen for manual operations or automatically provided via PC based Bridgeworks Software. Measurement and Uncertainty Analysis you need as a Metrologist that meets the requirements of ISO/IEC 17025 Accreditation for both Resistance and Current measurements! IEEE 488.2 is standard on all models with the universally recognized Standard...

Expanded Resistance Measurement Range: From 100 kO up to an expanded 1 GO range. There is no need to purchase a second - high resistance bridge and additional standards to cover the extended range of standard resisters. Need to go even higher? Add a Programmable 6530 TeraOhm Bridge-Meterto the system and have an automated system measuring all the way to 20 Peta Ohms! Current Extenders/Sources: You can extend your current capabilities all the way to 10,000 A, with modular 150 A and/or modular 1000 A precision current sources. This represents substantial setup and ongoing operating cost savings...
