WESTON CELL Meaning and
Definition
-
A Weston cell, also known as a Weston standard cell, is an electrochemical cell that functions as a highly accurate and stable source of electromotive force (EMF). It was invented and developed by Edward Weston in the late 19th century and is designed to provide a precise voltage reference for use in scientific and industrial applications.
The Weston cell consists of a cylindrical glass container filled with a saturated solution of cadmium sulfate (CdSO4) in water. Inside the glass container, there are two electrodes - a cadmium electrode and a mercury electrode. The cadmium electrode is surrounded by a paste of cadmium sulfate and mercury sulfate. An amalgam of mercury and cadmium is placed on the mercury electrode, acting as a reference electrode.
The cell produces an EMF of approximately 1.01864 volts at 20 degrees Celsius. This value remains remarkably stable over time, making Weston cells highly reliable and long-lasting voltage standards. They are often used as references for calibrating laboratory instruments such as voltmeters and other electrical measuring devices.
Due to their accurate and consistent output, Weston cells have been widely used in scientific research, electrical metrology, and telecommunications. They offer a known voltage reference that can be used for quality control, standardization, and accurate measurements in various fields of engineering and scientific disciplines.
It is worth noting that while the Weston cell has been an essential tool for precision measurements for many decades, more modern voltage references, such as solid-state devices, have started to replace it in certain applications due to advancements in technology.

Etymology of WESTON CELL
The word "Weston Cell" is named after its inventor, Edward Weston, an American chemist and electrical engineer. Edward Weston developed the Weston standard cell in the late 19th century. The Weston Cell, also known as the Weston Standard Cell or Weston Normal Cell, is a type of primary standard cell used for precise voltage measurements in laboratories.
