Objective

• In Industries, setting weight standards for samples allows for streamlined testing procedure and simplifies applications such as formulation, mixing or assessing a sample’s properties.

Operating Mechanism

• Scales determine weight by measuring the amount of force required to oppose an object’s acceleration due to gravity. As mentioned, scales are often used to weigh larger masses, such as raw materials, reagents, and products in a production setting. There are two main categories of scales: mechanical and digital.

• Mechanical scales: The mechanism of mechanical scales vary, but most commonly use a spring. The weight is applied and the measurement is shown by a moving dial. These scales allow for quick and easy-to-read measurements but are not considered very accurate.

• Digital scales: This type of scale employs the use of a special electrical circuit. As a weight is applied, the voltage within the circuit changes and a processor calculates the weight. Digital scales are more accurate than mechanical scales, can provide multiple units of measure, and can often be connected to a computer for easy processing of data.
