"The laboratory balance PCE-BS is a light, rugged precision balance suitable for different purposes. The removable stainless steel pan allows the laboratory balance to be cleaned easily. The CE-BS 300 and 3000 laboratory balance can be used for weighing as well as for piece counting. The calibration of this laboratory balance is done by means of external calibration weights (automatic calibration procedure) or in accredited laboratory (ISO calibration). The laboratory balance is equipped with four adjustable feet. If the balance is used in a laboratory, it can be powered by the external mains adapter (included). In case the balance is used as a mobile weighing instrument, it can be powered by AA batteries. This compact scale can be used to weigh the different components of a chemical mixture. The weight of all the components can be calculated when they are removed from the scale as a way of control. Taring (taring can be carried out several times) is made by pressing \"ZERO\" key on the display."
