Precision Balances

Types of Precision Balances

When we discuss precision balances, we are talking about a range of instruments designed for different capacities and readabilities. They include lab and quality control precision balances for standard laboratory applications, compact precision scales for measuring small samples with high precision, and fast response balances offering a blend of high precision and larger capacity. These high precision lab scale features, along with their calibration, sensitivity, and accuracy, make them indispensable tools for laboratories.

Maintenance of lab precision balances is also straightforward, ensuring they can handle rigorous daily use across different industries.

Purchasing Tips for Precision Balances

When shopping for high precision balances, look for the features that meet your specific needs. Consider the scale’s capacity, readability, pan size and calibration capabilities. Weighing-Net collaborates with top manufacturers to bring you a range of precision balances suitable for different applications. Keep in mind that the precision balance calibration process is a crucial aspect to maintaining the balance’s accuracy over time.

FAQs

Do precision balances and precision lab scales need wind shields? 

Contrary to popular belief, precision balances do not always require draft shields. Although wind shields can protect from environmental disturbances that might affect the reading, precision balances are less sensitive to such disturbances than analytical balances due to their lower readability. This means they can provide accurate measurements even without the use of draft shields in many laboratory settings. It is always important, however, to ensure that your specific setting and use case allows for accurate readings without a wind shield.

How to weigh a sample on a precision balance? 

To weigh a sample on a high precision lab scale, first ensure the balance is calibrated and levelled. Then, place the sample gently on the centre of the balance pan. Wait for the reading to stabilise before noting the weight, taking care not to exceed the scale’s capacity.

What is the smallest load I can weigh on my precision balance? 

The smallest load a precision balance for laboratory use can measure depends on its readability. Some high-precision balances can measure weights as small as 0.001g – like our Gram FC. 

How do I level my precision balance? 

To level your balance precision instrument, use the built-in spirit level and adjustable feet. Ensure the bubble is centred in the spirit level, adjusting the feet as necessary. Remember that a level balance is essential for accurate readings.

Do I need to calibrate my precision balance? 

Yes, calibration is crucial for maintaining the accuracy of your precision balance. Calibration ensures that the measurements you get from the balance are accurate and reliable.Additionally, some models, for example the Gram FV offer the function of automatic internal calibration. This not only saves you time, but also ensures that the scale is correctly adjusted and calibrated at all times.

How often do I need to calibrate my precision balances? 

The frequency of calibration depends on use, environment and the tolerances required for your measurements. For laboratories using high precision balances, it’s often recommended to calibrate the balance weekly, or even daily in some cases. Always refer to your manufacturer’s guide for specific instructions.
