Abstract
This invention relates to a portable quartz crystal microbalance, including: a piezo quartz crystal to be attached to an object to be measured; an electrical oscillator circuit for supplying appropriate energy to the piezo quartz crystal so as to output oscillating frequency corresponding to the object to be measured; a counter for counting the oscillating frequency and outputting frequency values corresponding to the oscillating frequency; a microprocessor for plotting an oscillogram corresponding to the frequency values according to the frequency values and outputting the same; a display device for inputting and displaying the oscillogram; and an input device for controlling operation of the portable quartz crystal microbalance.
