Precision balances generally deliver higher resolution accuracy over bench scales, but lower resolution compared to analytical micro balances. The precision balances are a preferred method of measurement where micro resolution is not required, and where air currents or temperature fluctuations may be present as they are less sensitive to these conditions.
What Are Some Common Applications of Precision Balances?
Precision balances can be used in numerous industries and application from research, quality control, pharmaceutical, laboratories, food and beverage, textile industries, chemical industries, educational and more.
Some of the roles of a precision scale in a laboratory are:
- Simple weighing
- Dynamic weighing
- Interval weighing
- Statistical quality control
- Sample preparation
- Formulation
Top-loading scales can also be used for weighing precious gems and jewellery such as gemstones, gold, and other metal or precious stones. Our GX-A Multi-Functional Precision Balance is capable of evaluating impact loads and offers quick response speed and high stability.
What are the Typical Functions of Precision Balances?
Some of the typical functions of precision balances are:
- Dynamic weighing
- Percentage weighing
- Parts counting
Some precision balances are designed with overload protection for enhanced durability. The functions of a precision balance vary depending upon the model you choose. Compact precision scales are ideal for laboratories. Our FX-i Series Precision Balance is one such scale that is compact, lightweight and commonly used for precision weighing in research and educational institutions.
Some balances and scales have a more heavy-duty construction with a higher IP rating and are specifically designed to withstand washdown environments and/or applications where spillages or fine powder debris may be present. The FZ-i-WP Precision Balance is an example of such a scale and is fully sealed against the ingress of foreign matter.
How to Choose the Best Precision Scales and Selection Criteria
When choosing a precision balance, consider the following factors:
Application: The major determinant is the purpose or application. What do you want to use your precision balance for and where? Will it be used for laboratory research, manufacturing, quality assurance, and such? This will guide you in knowing the type of weighing balance to go for.
Required capacity: Check the maximum as well as minimum weight the intended scale can weigh at a time. Ensure that it fits your application, and remember to include the weight of the containers that may be used.
Resolution: The resolution of a scale refers to the smallest increment that the scale can detect or display. For example, if the resolution of a scale is 0.1g, its increments will be shown by 0.1g at any given time. The resolution would determine the smallest changes in weight that can be detected, and the accuracy in your weighing process.
Features: Other considerations when choosing the right precision balance include the features or functionality. Do you need density determination, dynamic weighing, parts counting or statistical functions? Do you prefer internal or external calibration, and do you need an all-metal or waterproof scale? You might also want to check for compatible accessories, such as a printer, USB, and software.
Maximum Load
When selecting a precision scale, you must first identify the load requirements you need for your application. Precision scale load cells can measure weight ranging from milligrams to kilograms. Thus, check the maximum load capacity the precision balance you are buying is suitable for the capacity you require.
If your work requires products to be weighed that have significantly different resolutions, ie. 10kg x 1g versus 10kg x 1kg it is advisable to purchase two different scales rather than relying on a single scale.
Interfaces
Several precision scales available in the market offer built-in or add-on interfaces for transmitting the recorded data from the scale to another device. Though the cost of such products can be higher, they can provide some practical features that is extremely beneficial for the productivity of your work. The interface helps with outputting, storing, and evaluating the weighing data.
Pan Size
The pan size of the precision balances is an important factor to consider. First, evaluate the types of materials you will be weighing on the scale and how much surface area they will cover. Then depending upon the requirement, choose a compact or large platform scale that is suitable for your needs.
The weighing pan or platform must always be loaded centrally to record the correct value of the measurement. If you are weighing liquids or powders, make sure to use a suitable container that compliments the size of the weighing platform. It should not overhang the pan.
Durability/Warranty
Consider a precision scale that has long-lasting construction and is exceptionally durable. Also, review the warranty period of the product so that in case of any hardware defect, you can get an easy solution. Most precision scales usually offer a warranty period of at least 3 years.
Additional Features
Precision scales come in a wide range and different types can offer various useful functions that simplify the work of the user. Some of the features can include:
- IP65 Standard Waterproof Protection
- Internal Calibration Function
- Shock Absorption Function
- Fast Stabilization Speed
- Piece Counting Function
- Percentage Function and more

FAQs
What is the difference between an analytical balance and a precision balance?
While a precision balance generally measures to the nearest 0.1-0.01g, an analytical balance measures to the nearest 0.0001g. Precision balances usually have a higher capacity, though both can measure capacities of hundreds of grams to kilograms.
How often should I calibrate my precision balance?
It depends on several factors, including how often the balance is used, the environment it is in, and how accurate you need it to be. You should also check the manufacturer’s recommendations for the frequency of calibration. Generally, it is recommended that your precision balance be calibrated at least once a year.
Where are precision balances used?
They are used in a wide range of industries including laboratories, pharmacies, chemists, textile industries, and schools.
How will air draughts influence the accuracy of my precision balance?
Precision scales can become slightly inaccurate due to environmental factors including air draughts.
Simple actions such as the opening and closing of doors, and the use of air conditioners and fans, can cause changes in air draughts that may result in unstable readings.
What about temperature? How does that affect my precision balance?
Any slight change in temperature, even radiated heat from your hands, can affect the weighing results. The temperature of the environment and that of the sample you are weighing can also influence the accuracy of the result.
For an accurate reading, you may need strict temperature control.
