Description

QCM is an acoustical transducer that converts mass changes on the surface of an oscillating quartz crystal resonator into an electronic signal.It has been widely used in such areas as vapor deposition of metals, and over the last decade it has become more widely used in biosensor applications.

Typical dimensions are Dia:0.489” and Dia:0.550” , two frequency are 5MHz&6MHz fundamental mode and three shape:plano-plano/planoconvex/Biconvex;
Also with 3types electrode including Gold/Silver/Alloy .
