Weston standard cell definitions

What is a Weston Standard Cell?

A Weston standard cell is a type of electrochemical cell used as a stable and accurate voltage reference in metrology. It is named after Edward Weston, the inventor of the device. This cell consists of a saturated cadmium sulfate solution as the negative electrode and a mercury-mercurous sulfate mixture as the positive electrode. The Weston standard cell has a stable electromotive force of 1.018638 Volt at 20 degrees Celsius.

How Does a Weston Standard Cell Work?

When the Weston standard cell is connected in a circuit, it produces a stable and predictable voltage. This voltage remains constant over time, making it ideal for calibrating instruments such as voltmeters and potentiometers. The cell's design ensures that the voltage output is not affected by external factors like temperature or humidity, providing highly reliable and accurate measurements.

Applications of Weston Standard Cell

The Weston standard cell is commonly used in laboratories, calibration facilities, and industrial settings where precise voltage measurements are essential. It serves as a reference standard for calibrating voltage-measuring devices, ensuring the accuracy of scientific experiments, electrical tests, and quality control processes. The stability and reliability of the Weston standard cell make it a trusted tool in metrology.

Benefits of Using Weston Standard Cell
