FIELD: measuring engineering.
SUBSTANCE: method comprises measuring the rate of sedimentation of the oxalate calcium scale from the solution on the micro-pickup based on a quartz crystal and provided with the top side and second bottom side which is insulated from the solution where the solution pH value in the vicinity of the micro-pickup is measured with a pH meter and maintained within the range from 3.5 to 9. The device comprises working electrode covered with an conducting material or made of conducting material.
EFFECT: enhanced accuracy of measuring.
