Stanford Research Systems QCM25 Crystal Oscillator, 5 MHz

The Stanford Research Systems QCM25 is a 5 MHz crystal oscillator designed for precise mass and viscosity measurements in processes occurring at or near surfaces or within thin films. This oscillator is part of the QCM200 Quartz Crystal Microbalance system, which is widely used in various scientific and industrial applications.

Key Features

• High Precision: Measures resonant frequency changes as a linear function of the mass of material deposited on the crystal surface.
• Versatile Applications: Suitable for use in liquid or gas environments.
• Rugged Design: The crystal holder is compact and easy to use, ensuring durability and reliability.
• Automatic Gain Control: Provides the required signal amplitude to achieve series resonance and monitor energy dissipation.
• High Stability and Accuracy: Ideal for most experiments, with an option to connect a precision timebase for optimal long-term stability.
