Industrial scales are made to precisely weigh very high weight commodities that would otherwise destroy other small scales. The industrial scales from Arlyn Scales come with a digital indicator that displays the weight of the commodity on the platform. This digital numeric display is a feature that makes the Arlyn Scales unique. In addition to displaying the weight in easy to read fonts, this digital display allows the user to select the units for use, allowing the display to be read easily, eliminating the need for unit conversion after weighing is done.
Analytical balances provide weight measurements that are highly precise and very accurate. In fact, many analytical balances provide weights that are accurate to within .01 mg Ð high precision models can provide even more precise results. Because of the high degree of accuracy and reliability, they are popular among those professionals that need to rely on their results.
One of the reasons an analytical balance can provide such accurate measurements is the design. Typically a transparent box or enclosure surrounds the weighing pans. This enclosure creates an environment in which no additional forces can compromise the results. They protect the sample from dust, and even air currents that can throw off such a sensitive balance.
This same enclosure, along with a vented balance safety unit, uses acrylic airfoils. These allow the consumer to accurately weigh a sample without the interference of turbulence. In many cases, these same systems can be used to protect the user as they weigh samples that are potentially dangerous or caustic.
One downfall of the analytical balance is that the sample being weighed will ideally be at room temperature. If the sample is not, it is possible for air currents to develop inside the enclosure under the principle of natural convection. These air currents can subtly effect the results.
While all analytical balances are precise by design, there are a number of these specialized scales with superior performance. When purchasing an analytical balance, the user must carefully determine the degree of error that is acceptable. Differences in materials, workmanship and operation all contribute to the accuracy of the analytical balance. You should prioritize accuracy and price, and find the best combination of the two in an efficient analytical balance.
Analytical balances are used by a wide range of professionals. Chemists and pharmacists are just two of the many professionals that can benefit from a precision analytical balance.
If accuracy is your most important function, you will likely need a highly advanced balance. This is especially true if air currents or dust can effect your measurements. Examine other needs as well, such as the need for digital readouts, Bluetooth or USB connections, auto tare, and container tare functions.
While analytical balances are limited in overall capacity, some applications require weighing heavier loads with excellent accuracy. In these cases, ultra precision scales are available with capacities of up to 500 lb, with resolution as high as one part in 500,000. Surface Acoustic Wave (SAW) scales fill this need at very attractive costs.
