Product Overview

openQCM Wi2 is the entry level Quartz Crystal Micobalance, capable of monitoring frequency variation in real-time. A highly sensitive and very easy to use device, suitable to those who want to get started with QCM technology

openQCM Q-1 is an open hardware device capable of measuring mass variation on quartz crystal surface on molecular scale. The device is particularly suited for thickness monitoring and gaseous sensing, but can also be used in liquid environment.

The electronics interface based on an oscillator driver makes the frequency monitoring fully automatic, making the device highly sensitive and easy-to-use 

The modular design makes the device flexible. The main body is separated from the the sensor module, which features a practical and innovative enclosure system.

openQCM Wi2 is a truly plug and play scientific device. Each instrument is mounted and tested in order to guarantee the best performances.
