Theon Sensors' facility is located in the industrial zone of Koropi, close to the Athens International Airport within a property of 4.000 square meters, 1200 of which are occupied by the current building. Theon  is in the possession of the necessary building permit to double the production area to 2.400 square meters in case of a large increase of order inflow. In addition to this, the Singapore facility can be used to increase production. Furthermore, two new floors have already been built at Theon Sensors Headquarters in Koropi. The staff has moved to its new offices and all here at Theon Sensors are expecting our distinguished visitors to our new premises.
