The RQCM is a highly advanced method of measuring film properties during processes such as deposition, dissolution or permeation. it is possible to measure up to three crystals simultaneously with <0.4 ng.cm2 mass resolution. All data is logged and graphically displayed using custom WindowsTM based software in real time. 

At the heart of the RQCM is a high performance phase lock oscillator with measurement stability from 3.8 to 10 MHz. The circuit also incorporates adjustable crystal capacitance cancellation, reducing error caused by parasitic capacitance of the crystal. This is essential for accurate measurement of lossy (soft) films.
