6622A -XPS
Direct Current Comparator Bridge
0.03 ppm of best uncertainty, The Performance Enhanced 6622A-XP


GUILDLINE INSTRUMENTS 6622A SERIES direct current
comparator (DCC) bridges are well suited for precision
calibration in both resistance and temperature
applications. Their flexible and wide measurement
ranges, the upgradeable performance, the newly
introduced 100:1 measurement ratio all make them very
attractive to users. Due to customers' request, Guildline
introduced the model 6622A-XPS, the performance
enhanced version of the Guildline model 6622A-XP. The
only difference between a model 6622A-XPS and a
model 6622A-XP is the enhanced performance of model
6622A-XPS, the best uncertainty of the model 6622A-
XPS is better than 0.03 ppm.
Specially selected hardware is used in the construction
of the model 6622A-XPS. In addition, a much more
stringent alignment and calibration procedure also play a
6622A SERIES FEATURES important role to guarantee the performance of the
model 6622A-XPS, to reach the 0.03 ppm of uncertainty
Measurement Range From 1 m~134 at both 1:1 and 10:1 ratios.
k Just like all the other 6622A, the model 6622A-XPS can
be upgraded, to have a wider measurement range of up
Extended Measurement Range down to
to 100M or 1G.
