Black magnetic ink, pre-mixed, high sensitivity.
Ardrox 800/3 consists of very finely divided black magnetic particles suspended in high flash point odourless kerosene designed to provide good particle mobility. The black particles have been selected for their high magnetic response, low coercivity (to avoid coagulation) and prolonged operational life.
