Precision scales with resolution from 1mg
A precision scale is a special type of scale that can make very accurate measurements. Precision balances generally have higher resolution and accuracy than traditional balances. They are commonly used in scientific, medical and industrial applications where highly accurate measurements are required.
Precision balances are available in a variety of capacities and accuracies from milligrams to kilograms. They are commonly used in laboratories and research facilities to weigh small quantities of materials such as chemicals and pharmaceuticals. Industries can also use precision scales to manufacture food, beverages, cosmetics and other products where accurate measurement of ingredients and substances is important.

How is a Precision Scale constructed?
Precision scales typically consist of several components that work together to provide accurate measurements. The main components of precision scales are:
Load Cell
The load cell is the heart of every precision scale. It consists of a strain gauge connected to a metal alloy. When a weight is placed on the scale, the strain gauge stretches, changing the electrical resistance. The load cell converts this change into an electrical signal processed by the scale's electronics.
Platter
The platter is the surface on which the object to be weighed is placed. It can be made of various materials such as stainless steel, glass, or plastic and has a smooth surface for accurate weighing.
Electronics
The electronics of precision scales include components like microcontrollers, analog-to-digital converters (ADCs), and displays. A microcontroller controls the operation of the scale and processes signals from the load cell and the ADC. The ADC converts the load cell's analog signal into a digital signal that the microcontroller can process. The display shows the weight of the object on the scale.
Calibration Weights
Precision scales need to be calibrated regularly to ensure accurate measurements. Calibration weights are used to calibrate the scale to a known mass and verify the accuracy of the scale.
Housing
The housing of the precision scale protects its components from dirt, dust, and other environmental factors. It can be made of various materials, including plastic and stainless steel.
