BIOPRODUCT IONOMETRY METHOD AND DEVICE FOR IMPLEMENTING SAID METHOD Russian patent published in 2010 - IPC G01N27/416 

FIELD: physics.

SUBSTANCE: method according to the invention involves measurement of electrical parametres of the measured medium of the product using a probe. Ion content of the food product is determined using a formula which links voltage across the probe in the absence of effect of the measured medium of the product on the and a high-frequency signal at the input of the probe; the voltage value at the input of the probe when the high-frequency signal is transmitted to the input of the probe, but without effect of the measured medium of the product on the probe; voltage value at the input of the probe when the high-frequency signal is transmitted to the input of the probe and exposing the probe to the measured medium of the product and the calibration factor. Proposed also is a device for implementing the method, which has an indictor in form of a display, as well as a processor, two pulse converters, a time-proportioning on/off controller block, an amplitude detector and a modulator. The processor is connected to two pulse converters, the display, time-proportioning on/off controller block, modulator and amplitude detector. One pulse converter is connected to the display and the other to the time-proportioning on/off controller block, amplitude detector and modulator. The modulator and amplitude detector are also connected to the probe, and a power supply is connected to the processor and pulse converters.

EFFECT: higher accuracy and stability of measurement.
