FIELD: agriculture.
SUBSTANCE: device has measuring and controlling channels of registration. The measuring channel includes a helium-neon laser, a metal mirror and a bush with marks made on its surface of fixed pitch. The measuring channel also has a photodiode in series with an amplifier, a delta function block, a detector and an analyser. The controlling channel is formed by series-connected inductive sensor, former, gate circuit, calculating-analysing device, recorder and display unit.
EFFECT: use of measuring and controlling channels in the device ensures output of quality information on the value and imbalance point in dynamic mode of diagnosis.
