Condition: excellent (used), Year of construction: 2017, functionality: fully functional, input voltage: 230 V, We are selling our Primescan 3D scanner with two sensors. It is a demo unit with minimal usage for actual measurement. Very good condition, with every original accessory. It comes with two sensors and one controller, which means that only one sensor can be used at once: 1. R8-FOV500 (8MP sensor with 500mm field of view) 2. R5-FOV200 (5MP sensor with 200mm field of view) It comes with one controller, so only one sensor can be used with controller at the same time! If you need the second sensor for the measurement, you need to change the sensor only, but everything else stays the same: with this configuration you can choose between two resolutions and field of views: if you need to scan smaller parts (up to ca. 200mm) you can use the R5-FOV200 sensor, and when you need to scan bigger parts (up to ca.500mm) you can use the R8-FOV500 sensor. Parts of the system: 1. Sensors: R8 FOV500 and R5 FOV200 2. Controller Ksdeumawgspfx Akijnc 3. Tripod 4. Turntable 50, 50kg load capacity 5.
