PIEZORESONANCE ANALYSER FOR MASS OF DRY RESIDUE OF WATER AND AGGRESSIVE LIQUIDS Russian patent published in 2011 - IPC G01N29/00 

FIELD: physics.

SUBSTANCE: piezoresonance analyser of the mass of dry residue of water and aggressive liquids has a piezoresonance sensor, a frequency meter, a holder, a heater, where the analyser has in one housing a piezoresonance replaceable sensor with a limiting barrier in form of a ring made from a moisture-resistant polymer deposited on a quartz surface fixed in one holder with a resistive programmable microheater, electronic units for measuring frequency, converting frequency, controlling temperature of the heater and heating time, an accumulator power supply and an LCD display.

EFFECT: design of a portable device with self-contained power supply which enables to cut analysis time and simply the analysis process without lowering analytical characteristics of the method.
