Inquiry (采购产品): 5 mg replacement weight I want to puchase a replacement 5 mg weight for my calibration set (Catalog #854252.1) with a certificate. Would you send me a quote for this weight and if you sell this individually or does it come with a set? **** Hidden Message ***** Ruseell Evans 95605 Company: TestAmerica E-mail: russell.evans@testamericainc.com **** Hidden Message ***** russell.evans@testamericainc.com
