Precision Balances

Precision laboratory balances, also called top loading balances, are a form of scale designed to offer highly accurate results, within the sub-milligram range. Used for the measurement of small samples, precision balances provide an accurate, quick, and simple way of determining the weight of items such as particulate matter. Electronic precision balances offer a wide range of weighing capacities, with maximum capacities up to 64 kg. They allow readability in the range of 1 mg (0.001 g) to 1 g, or 0-3 decimal places. High precision laboratory balances can extend this accuracy to 4 decimal places, on the display of the precision balance, 0.0001g (0.1mg) increments are used.

Precision balances produce steady readings in a wider range of environmental conditions than analytical balances which must always be used under strict conditions to ensure accurate readings. Being less sensitive to temperature fluctuations and air currents, precision balances can serve as the more convenient method of measurement. While a draft shield is not always necessary for the accurate use of a precision balance, when working in a fume hood or under normal conditions with a high-resolution precision balance of 1 mg readability, one should be employed to maintain performance.

A precision balance calibration assesses the behaviour of the chosen instrument. Calibration should only be performed by an authorized service technician. An adjustment changes the behaviour of a weighing instrument and requires an intervention which, in most cases, permanently alters the measuring instrument. Adjustment should not be mistaken for calibration, the terms are not interchangeable, and calibrations should always be performed after any adjustment procedure made to the balance. Many times people refer to "calibration" when "calibration and adjustment" is more accurate.

In many cases it is, in fact, the results of a calibration procedure that indicates a need for an adjustment or other repair to be made. After the adjustment or repair is complete, the calibration procedure should always be repeated to verify the proper measurement relationship has been re-established. In between regular calibrations by a technician, routine testing by the user should also be made using two external weights. These user tests allow for early detection of potential issues and deviations from weighing process requirements.
