Weighing scales and balances are expected to provide accurate and precise measurements. But in categorizing weight scales used for various industrial applications, the term “precision scale” pertains to an entire classification of weighing scales.
What is a precision weighing scale?
Precision scales are usually defined as a scale or balance used measuring the weight of quantities in small increments all the way to a precise number. The typical measurement range is up to one milligram. Precision balances or scales are also called “top loading scales”. The weighing capacity of precision weight scales varies from grams to kilograms. These types of scales offer a more precise reading than bench scales but are not entirely as accurate as analytical scales. In contrast, analytical scales have a higher weighing capacity, but lower readability.
Typical applications of precision scales
There are many valuable uses for industrial precision scales. Most notably, high precision balances have the capacity and durability for testing materials used in construction sites, such as concrete, in order to get scientific measurements. Scientific laboratories also use precision weight scales all the time in capacities involving the measurement of chemicals and compounds used for biological research.
Apart from construction and laboratories, precision scales are also useful in the pharmaceutical and medical fields. The high readability, measurement range, and capacity of these balances allow for measuring volatile compounds and samples of different sizes.
Another field that uses precision scales is production facilities such as factories involved in manufacturing. Lastly, precision scales are also useful in jewelry fabrication for weighing precious metals like gold and silver as well as gemstones.
Specific functions and features of precision weight scales
Unlike typical bench scales, a precision weight scale tends to have more functions and features. Most models include weighing density and below-balance measurement. Some even have the capacity to communicate with computer and digital interfaces. Precision weight scales also have multiple weighing functions such as percentage, parts counting, and dynamic weighing. These scales also have overload protection to prevent damage and premature wear and tear.
The functions and features of a precision weight scale depend on the brand and model. Some models are compact enough for classroom and laboratory instruction, while there are others that are large enough to bring for field use.
Choosing a precision weight scale
Before you start browsing your precision weight scale options, you need to consider the intended use carefully. This category of weight scales is diverse enough to provide for different capacity, readability, size, and functional requirements. Sturdier precision balances are ideal for industrial or commercial applications, while there are smaller scales perfect for low-impact applications like in laboratories and classrooms.
It is also essential to research the brand and manufacturer so that you can read reviews and feedback from other buyers. As much as possible, compare the features of each model you are considering so that you can select the most suitable precision weight scale that has the features and functions needed to meet the specifications of the intended application.
