AC Adapter for PS500 Scale
$35.00
The AC500NEG is to be used with older scales that have a negative power supply. When ordering please be sure to verify which adaptor you have a pos or negative one. Generally scales purchased before June of 2013 will need the AC500NEG. Take a look at the image and check for the matching polarity, this can be found on the bottom of the adaptor next to the LPS.
