6622A Series -Direct Current Comparator Resistance Bridges

Resistance Measurement –Automatic DCC Resistance/Temperature Bridge

Product Description

introduces new design concepts and the best in measurement uncertainties for Direct Current Comparator (DCC) Resistance Bridges 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 and high ohms measurements without having to purchase two separate 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.

You can start with the low-cost 6622A base DCC Bridge with measurement uncertainties down to 0.1 ppm and measurement range to 100 kΩ. Workload requirements demand better measurement uncertainties or range? Then you can move to better uncertainties with an eXtended Performance (XP) or eXtended Performance Special (XPS) Models or improve both range and uncertainties with the eXtended Range (XR) model or even the best of the best the High Voltage Model (HV) with uncertainties down to 0.04 ppm and a measurement range of 1 GΩ with voltage to 1000 Vdc. The 6622A Series Provides the
