A high precision balance is an advanced weighing instrument that performs to a very high level of accuracy, making it ideal for demanding laboratory applications in chemistry and research. These weighing instruments are also frequently used in the food and beverage industry to measure ingredients, additives and spices during recipe formulation and production processes.
The sensitivity and capacity of a high-precision balance can vary, depending on its intended application. The sensitivity of a device is determined by its smallest increment, known as the “resolution”. A higher resolution indicates greater accuracy, and therefore, a more precise and sensitive balance.
Generally, high-precision balances have a sensitivity of 0.01 grams (1 milligram), with a range of capacities up to several kilograms. This makes them suitable for a wide variety of laboratory and industrial tasks, as well as for applications in which the precision of a reading is not essential.
Another important consideration is the environmental conditions in which a high-precision balance will operate. The temperature of the ambient environment can affect the readings of a scale, so it is recommended that a high-precision balance be kept in a room that is at a consistent temperature and humidity. This can prevent fluctuations in weighing results that may be caused by the changes in air density.
It is also necessary to establish a proper equipment maintenance and cleaning schedule for any high-precision balance. This helps to keep the weighing surface clean from contaminants and other substances, as well as maintain a consistent calibration between multiple units of measurement.
