No two scales are alike. They differ on capacity, accuracy, and construction. These qualities contribute to the overall functionality of a scale as to whether it measures correctly or not. It is important to consider this when trying to find affordable scales that are right for business or laboratory use.
Differences in Scales
There are many kinds of scales. Each one is designed with different capacities and accuracies for specific jobs. Some are designed for more delicate work in microgram ranges while others are constructed to meet heavy-duty industrial uses in kilograms
Within these ranges, there is also a difference between digital and mechanical scales. Digital scales utilize a special circuit that when weight is applied, the voltage of the circuit changes. A processor inside the device then calculates these changes as mass in the appropriate units. Digital scales are designed for small to large scale use where accuracy of measurements and computer access to data are critical.
Mechanical scales vary but typically utilize a spring. When a weight is applied to the spring, a dial moves on a precalibrated dial to show the measurement. Mechanical scales are typically easy to use and quick to read but provide poor accuracy and require manual integration of data for computation.
Digital scales are preferred over mechanical scales as they can provide various units of measure, have auto-calibration, and make computation much easier.
Deciding on the Right Scales
The first thing to consider is the accuracy, or resolution, needed for measurement. The resolution of scales is whether they read every 1 mg, or every 1 g, or larger. The second thing to consider is the capacity. This is the largest weight that can be measured. For scales that have lower resolutions, those closer to 1 mg, the capacities are also proportionately smaller. This means to measure larger quantities at that accuracy, they will need to be measured in batches.
After considering these first two qualities, other factors can help decide whether the scales are affordable and beneficial. The third most important thing to consider is auto-calibration. After the scales are turned on, the processor determines the base voltage for no weight. This helps to speed up taking measurements without having to weigh standard weights. Some scales provide computer integration through a serial port or USB port. This is useful for taking data continuously without needing to write it down by hand.
After taking these qualities, finding affordable scales can provide accurate measurements. This can help ensure businesses or laboratories that their production lines and experiments are producing correct results. Having to reproduce a product or to reperform an experiment would cost more time and money in the long run.
