FIELD: food industry; chemical industry.;SUBSTANCE: device can be used for measuring limit shift voltage in food and non-food products and raw materials. Device for measuring longitudinal shift stress is provided with cone submerged into tested sample; submerge depth analyzer; submerge depth electronic registration circuit. As the submerge depth analyzer, photodiode is used and light-emitting diode, attached to cone. Photodiode is capable of discrete movement relatively light-emitting diode.;EFFECT: small sizes; low cost; improved precision of measurement.;3 dwg
