AD-1683 DC Static Eliminator
The eliminator is able to dissipate static electricity on a
charged sample.
The eliminator does not use a ventilator and can be used

Enables bi-directional communication between the PC and the balance when a USB driver is
installed.
Can use serial communication software such as WinCT on a PC without COM ports.
An RS-232C cable is provided to connect the USB converter to the balance.
