QCA922A
QCA922A
Essential product for mass change detection.
The Quartz Crystal Analyzer 922A is our entry level QCM for basic applications, requiring no measurements at overtones, or temperature control.
The instrument monitors both the resonant frequency and the resonant resistance, which are also reflected on the two analog outputs. It is possible to connect the QCM device to a Bio-Logic potentiostat using a DB9‑8BNC cable (catalog n°: 092‑22/1).
