We apologize for the slow delivery and thank you for your patience.

voltagestandard.com had its origins in 2007 with the publication of our Nuts and Volts magazine article, "Build a .01% Accurate Voltage Reference"
http://nutsvolts.texterity.com/nutsvolts/200709/?folio=52.  Since that time we have added products and now manufacture reference assemblies that utilize voltage reference IC's from Texas Instruments (REF5050ID) and Linear Technology (LT1021BCN8)


Our product line consists of several DC voltage references and a DMM checker
