Not only used on Q-sense QCM-D, also used on many other EQCM plateform such as Gamry, AWS and so on.

90% of sensor crystals are made in our factory now in the world, no matter where you buy, they made in our factory, why not buy directly, this will make less mistake on communication and more fast.
