Ntega Aura




Product Features

  • NTEGRA Aura allows measurements in low vacuum environment – 10-2 torr with the following advantages. Due to a cantilever Q-factor increase measurements are more sensitive, and they are possible without bad influence of surface adsorbate.
  • Additional possibilities are provided by a temperature table with sample heating up to 300 °C and the accuracy of temperature maintenance 0.05 °C.
  • Measurements in a controlled gas atmosphere are possible as well.
