Semia is a French company specialized in design and maintenance of Vibration Analyzers dedicated to aircraft maintenance (helicopter and propeller aircraft). Semia has its own product range, developed thanks to its many certifications (PART 21J APDOA, PART 21G POA, PART145). Semia's product range will allow to all MRO centers (civilian or military) to perform its aircraft fleet Vibration Analysis. Semia developed its product range with the goal to simplify MRO centers maintenance tasks while reducing acquisition price (through multi functions and full compatibility with sensors and cables on the market). Since 2004, Semia owns a Full Maintenance Contract with French Ministry of Armed Forces for all its Vibration Analyzers fleet (calibration, repair, update, upgrade, logistics, training...).
