Inquiry (采购产品): Class S weights Calibration Hello! We have a very good set of Class S weights that need we need certified. (.1-50gm) As you can understand, we are concerned about putting them in the mail, etc. If we brought them to your location, could you do them while we wait? If so, what would the charge be and when would you be able to do them? Thanks much.
