Balzers QSG 201 Quartz Crystal Thin Film Monitor

The Balzers QSG 201 is a quartz crystal-based thin film deposition monitor designed for precise real-time measurement of film thickness and deposition rate in vacuum coating systems. It is commonly used in PVD processes where accurate layer control is essential. Measurement principle: Quartz crystal microbalance (QCM) Crystal frequency: Typically 6 MHz Measurement range: 0–9999.999 nm or Å (depending on configuration) Rate display range: 0.1 to 999.999 nm/s or Å/s Sensor inputs: Single or dual sensor head capability Resolution: High precision (0.001 nm or Å) Display: Digital LED or LCD (model-dependent) Outputs: Analog and/or RS232 (for integration with control systems) Power supply: 115/230 V AC selectable, 50/60 Hz Operating temperature: 0 to 45 °C Mounting: Rack-mount or bench-top Applications: Vacuum coating systems, PVD, sputtering, evaporation processes Features: Automatic zeroing, acoustic crystal failure alarm, deposition rate control interface Manufacturer: Balzers (now part of Oerlikon Group) Please review pictures carefully and let us know if you have any questions!
