Semi-micro balances with resolution of 0,01 mg and a built-in ioniser, which ensures accurate sample preparation. Static charges accumulate in different samples that are routinely weighed in the laboratory. These static charges can build up and alter the weighing value. By blowing ions, the built-in ioniser neutralises static electricity and within seconds the sample is ready to be weighed. The balance calibration system automatically calibrates the balance when there is a temperature change or at a set period of time (factory settings), this ensures accurate measurements even if the user has not manually calibrated the balance. All models have a stainless steel top pan.
