GUILDLINE INSTRUMENTS 6622A SERIES introduces new design concepts and the best in measurement uncertainties for Direct Current Comparator (DCC) Resistance Bridges manufactured by anyone today. Unique innovations in 6622A 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.

The 6622A Series modular design allows you to buy what is required today with existing budgets, and when workload requirements change, simply expand your bridge to meet these requirements without any loss of your original investment! Modular design provides a ONE BRIDGE solution reducing life cycle costs not only for equipment support, but also for software development and technician training. Modular design provides the perfect solution for current and future needs, whether you need secondary uncertainties or a Primary Laboratory Standard.

The concept and implementation is easy. You can start with the low-cost 6622A Base DCC Bridge with uncertainties down to 0.1 ppm and measurement range to 100 kΩ. Workload requirements demand higher measurement range? Then start with the eXtended Range (XR) model with its measurement range to 100 MΩ. You can move to better uncertainties with an eXtended Performance (XP) or eXtended Performance & Range (XPR) models. You can even start with or upgrade to the world’s leading High Voltage Model (HV) with uncertainties down to 0.02 ppm and a measurement range of 1 GΩ and with built-in voltages to 1000 Vdc.

The 6622A Series Provides the Best Measurement Specifications, Widest Range of Options, and Most Innovative Modular Design of Any Commercially Available DCC Bridge!

If you already own the base model, Guildline can upgrade this unit to provide extended range, extended performance or even improve both range and uncertainties. The choices are yours and designed to meet your workload, not ours! Best of all, your current software programs will work and the menus will be the same, thus dramatically reducing learning curves and training requirements. Ongoing operating costs are also dramatically reduced because a ONE BRIDGE series offers reduced support costs when the time comes for calibration.

Available Bridge expansions for all models include external current range extenders at 3 A and 10 A and at 150 A increments up to 10,000 A, internal voltages to 1000 Vdc, and complete temperature capability. Or simply invest in the best from the beginning!

The unique design is based on over 30 years of knowledge and experience in building DCC Bridges. Innovation abounds and your Investment is protected. When you buy any 6622A Series Bridge it’s as if you know them all. Menu operation, measurement setup, measurement operation and software are identical among all models. When you want extended range or enhanced performance – you still have only ONE BRIDGE to support for calibration. Just look at the models and expansion paths available for you with the 6622A Direct Current Comparator ONE BRIDGE Series.
