Hege, there is no actual calibration of the thermocouple itself. You can however verify that they read correctly. Heller sells an option on their reflow ovens specifically for this purpose. I hoping that someone chimes in here that is NADCAP certifi

unfortunately I don't. Our maintenance guy has done all of the repairs on our ovens. When we did have a DOS HELLER, I called HELLER about an issue and they said that nobody that still worked there has any knowledge of the DOS machines and they coul
