A static eliminator also called ionizer or electrostatic eliminator is a device which can neutralize static charge by generatingpositive and negative ions that offset the existing imbalance of ions . 

If we take ions with us , we may attract dust and airborne particles. And it may take into working space which could take damage to the products especially for electronic parts .

Voltage application systems utilizing corona discharge are constructed from: needle shaped electrodes that apply a high voltage; a high voltage power source; and grounding electrodes. Applying high-voltage to the electrodes produces a corona discharge on the needle tips.

When a corona discharge occurs and the air surrounding the electrode needles is broken down, ions are produced.

Using these ions, reverse-polarity static electricity is neutralized, and static is eliminated.

It's easy, hand-held, battery-operated instrument that indicates the surface voltage and polarity when held 1 inch away from the object. Another easy and quick method to check for proper operation of a Static Eliminator is to sniff for the presence of ozone near the device's emitter point(s)
