Con el goniómetro mardtb traemos todas aquellas características agradables que los usuarios conocen de las líneas de luz de sincrotrón al laboratorio domestico. Ofrece un grado muy alto de automatización. Prácticamente todos los movimientos son motorizados. Todos los motores son controlados por un microprocesador que puede ser operado a través de una interfaz Ethernet desde un ordenador.
Opcionalmente, el mardtb puede ser controlado desde un dispositivo móvil (Android, iOS próximamente). Consulte la página de la aplicación mardtbapp para obtener más información.
