Have you ever realized how much we depend on machines? We need machines to do almost all of our work, and that’s not bad, because somehow it’s the only way to keep this fast-moving world going. Among these machines are balances or balances, but they are also one of the most neglected objects. We may not realize it, but we do almost everything calculated and weighted, so we need the scales most of the time.
The precision scale is the object’s weight, using a counterweight that moves along the scale marked on the elongated arm. As the name implies, a precision scale is used to find the precise weight to a very small unit. That’s why the capacity range of these scales starts from a small figure like a gram and goes up to several kilograms. Therefore, you need to make sure that the range of capacity of the scale you are buying covers your required range.
Along with the range of capability, another thing to consider is the readability of the precision scale. Readability is the extent to which the results will be balanced and accurate. This need for precision is an extremely critical feature and more important than the range of ability. Indicate the degree to which your result is accurate. For example, if the readability of an accuracy scale is said to be 0.001 grams, it means that the scale will show the result up to one thousandth of a gram, and the maximum deviation of its reading from the original measurement is 0.001 grams. The higher the readability of a scale, the more sensitive it is. But you should not mix the terms readability range and capacity range; If readability is said to be 0.001 grams, that does not mean that it will measure an object 0.001 grams. The capacity range determines the lowest and highest weight limit.
Precision scales are very sensitive and delicate and can be affected by changing physical quantities such as time and temperature. This is why precision scales usually come with special adjustments to give the best result at all times. The four main types of settings are: proFACT, FACT, internal and external manual. All of these options are created to ensure levels of accuracy. A brief introduction to this configuration is as follows:
PROFACT: It is the automatic adjustment of time and temperature.
FACTOR: It is also automatic and temperature controlled.
Internal Manual: As the name implies, it is the adjustment made manually according to the internal weight of the machine.
External manual: is the manual adjustment made according to the external weights.
Precision scales have different styles and have different weighing sizes. Consider your purpose when choosing a precision scale. Weighing trays can be shaped like a cup or flat plate.
There are several websites that offer free comparison of the specifications of different scales and I think they are useful if you don’t know exactly what you need. Plus, with precision scales, you sometimes get optional accessories like test weights, gloves and other tools. These things make the deal very appealing, but they are secondary to the real scale and quality.
