QCM200 Quartz Crystal Microbalance uses an intelligent technology to measure mass and viscosity in situations where they occur at or near surfaces, or within thin films. Device is equipped with a controller, crystal holder, crystal oscillator electronics, three quartz crystals, and Windows / Mac software. The system can read the resonant frequency and resistance level of a 5 MHz, AT-cut quartz crystal. The linear function of the mass of the material on the crystal surface is related to resonant frequency changes. Depending on the resonance changes with the viscosity/elasticity of the material (film or liquid) when it comes in contact with the crystal surface, the resistance also changes.
