Guildline’s 6664C Low Thermal Quad Resistance Scanner is the first commercial scanner capable of operating at 1000V. This has greatly improved the measurement/calibration throughput of standards laboratories, since many high ohm measurements can now be automated. High ohm measurements are typically hard to make and very time consuming because of the low signal/noise ratio. With a Guildline model 6664C scanner and software, these hard-to-make high ohm measurements (up to 100 MΩ) can be automated and scheduled at any time that is convenient to a metrologist, even at night and over the weekends. This scanner is designed to work with a Guildline 6622A or 6640 Automatic Direct Current Comparator (DCC) Resistance Bridge Series, or our model 6622T or 6640T Temperature Bridge Series. Still have an older Guildline Automatic Bridges such as a model 6675A? Our software and scanner also supports all previous Guildline’ models.
