A truly Plug and PLay Instrument

OpenQCM is ready to be used with quartz crystals in the range from 1 MHz up to 10 MHz (default). It’s possible to vary the sensitivity of the system according own specific purposes.

One only device capable to operate in liquid, air or vacuum.

An integrated temperature sensor.

The control unit is an Arduino Micro. It is equipped with firmware for which the source code can be freely downloaded and editated. The proximity electronics controlling sensors is designed to be a perfect Arduino Micro shield. It’s an integrated circuit for the control of a wide range of resonance frequencies.

high stability and accuracy

openQCM is a real scientific instrument featuring performances comparable with those of commercial "close devices"
