Platinum 5 MHZ QUARTZ SENSORS BOX - 5 PIECES
openQCM
$286.80
AT-cut piezoelectric quartz crystal vibrating at 5 MHz and placed between 2 platinum (Pt) electrodes for electrical connection. The quartz crystal surface is flat and carefully polished. The Platium electrode adhesion is enhanced by using a substrate of titanium. 5 pieces in a box.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.
