Description

ntegrated Antistatic Ionizer

The antistatic ionizer, with which XA 4Y.A analytical balance is equipped, neutralizes electric charges inside the weighing chamber upon placing the sample in it. The ionizer neutralizes uncompensated electric charge accumulated on weighed object. The lower relative humidity and a reading unit of the balance, the more evident influence of static electricity. The influence of static electricity gives greater repeatability error, often also greater error of indication.
Measurement errors, due to the harmful effects of electrostatics, often reach the value of thousands of reading units and more. The problem concerns non-conductive samples, e.g. glass flasks, paper filters, plastics, etc.

Antistatic ionizer implemented in XA 4Y balances, due to the application of modern technology, compensates both cations and anions. The ionizer activates when the microbalance door opens, and deactivates when the door is closed. It is possible to control ionizer operation using weighing instrument panel. The operation is signalled by blue LED diode which emits light when the ionizer is on.
