Optima Plus carries internationally recognised approvals for both hazardous locations and performance, including European (ATEX), international (IECEx), North America (UL), Canada (CSA and FM), Marine (MED, BV, DNV, Lloyds and ABS) and Russia (Eurasian Customs Union). Additionally Optima Plus has been approved to SIL2 by renowned certification body TÜV Rheinland.
