Abstract :
A CdSO4 and Cd-amalgam based cell with an EMF of approximately 1.015 mV at 20°C is considered. Research showing that the cell is highly stable and reversible is reported. The EMF-temperature hysteresis is very small, and the reversibility is very good during charging and discharging. The cell can be used as a practical 1-mV reference standard for EMF. A millivolt cell has been constructed as a 1-mV secondary standard within ±5 mK. The characteristics and construction of the standard cell are reported
