Temperature fixed point cells are ITS-90 primary standards that demand low uncertainty measurements for calibration purposes. Traditionally, fixed-point cell measurements have been handled by resistance ratio bridges. Ratio bridges have several advantages, but they can be temperamental, susceptible to electromagnetic interference, difficult to repair, and require specialized equipment to verify their continued performance.
