Antistatic ionizer is used to remove overflow of mainly plus ions from the load and elements of a balance and the environment. Electric charges of the air are neutralized by the ionizer enabling a quasi-balance of plus and minus ions.

Unbalance of plus and minus ions in the air frequently cause unwanted electrical influences (attrition or repulsion) of elements which are in small distance to each other. It is a usual phenomenon for no-conducting materials (i.e., plastic, glass). As some balance elements are made of plastic and glass, this problem can considerably affect their operation and measurement results. The influence of electrostatics appears in the form of multiplied repeatability error or as multiplied repeatability error of indications.
