Product Overview
AT-cut piezoelectric quartz crystal vibrating at 10 MHz and placed between 2 gold electrodes for electrical connection. The quartz crystal surface is flat and carefully polished. The gold electrode adhesion is enhanced by using a substrate of titanium. Each sensor is preserved in a practical protective container, has single side electrode contacts and it is compatible with old openQCM and the new RF-spring contact system.
