When most people talk about an analytical balance, they are talking about weighing small qualities of the material and not large samples. As the sample size may be extremely small in labs or testing facilities, these types of scale have to have a very high level of precision.
Analytical balances are also designed to limit atmospheric or environmental factors from impacting the weighing process. They usually have an enclosure around the scale platform that prevents any air movement to either disturb the sample or to create deviations in the weight.
If you are in the process of choosing analytical balances for a lab, testing or production facility, there are a few important factors to keep in mind.
Precision and Accuracy
All balances on the market are sold with information on the actual weight range and capacity for the scale. It is important to consider that the smaller the range of weight for the scale the more accurate and precise it will be, which is always a key determining factor.
Having more than one balance with different weight ranges may be the best option in a lab or facility where a large number of different samples are processed and weighed.
Display or Remote Data Collection
Different models of analytical balances will either have a display on the unit itself, or they will transmit the data. When there is no display, the scale will use a variety of wireless or networked connections to send data through to your software program.
The scales with the display typically have controls at the scale as well, allowing operators to quickly and easily tare, zero or change units. In addition, these types of balances also have either a USB, wireless or other port to allow for data collection throughout the system.
Most of the balances are small in size and have a limited footprint within the lab or testing facility. Choosing between different models and option should include requirements, additional features that add value and the reputation of the scale for accuracy and precision.
