产品概述: 7000S 10-Volt External Reference Input Module
Include External references in Nanoscan scan sequence
Plugged into a Nanoscan mainframe, the Model 7000S provides a pair of input terminals that can be connected to any reference source with an output voltage in the range 10V ± 10mV. Once connected, the external reference is automatically included in Nanoscan scanning sequences, where it is compared to the Average output.
Automation benefits for existing standards
The 7000S is a simple way of maintaining traceability to existing 10-Volt standards, or certifying external standards, while taking advantage of all the process automation benefits that the Nanoscan system brings.
Less than 0.05ppm measurement uncertainty
An input resistance in excess of 10Ohm eliminates loading effects. Low thermal emf terminals and high-purity gold connections through to the Nanoscan measurement unit ensure less than 0.05 ppm uncertainty.
Compatitible with Nanoscan or Transref chassis
One or more 7000S scan modules can be plugged into a Nanoscan mainframe (or a Nanoscan/Transref unit used as an extension chassis).
