This is a genuine Weston Instruments Model 3 laboratory primary calibration Voltage standard. It is used in many metrology labs all over the world. This Weston design is the workhorse of the industry. This is a single fluid voltaic cell, uses saturated solution of cadmium sulphate. The negative electrode is cadmium amalgams. The positive electrode is mercury. It keeps a stable absolute voltage which provides a constant 1.0194 Volt abs. at 20 C°. These calibration voltage standards are not to be used to supply any current. They are usually used within a Wheatstone bridge along with a potentiometer or similar instrument.
