FIELD: physics. ^ SUBSTANCE: invention relates to quality evaluation of products of animate and inanimate nature, namely to biological quality evaluation of food products for a man, animal feeding staff, food supplements and other substances contacting human organism, natural and waste water, fisheries water, soil and ground. Besides, invention can be used to evaluate degree of different illness severity of a man and animals. Device for evaluation of products of animate and inanimate nature consists of biodetector contained in dust- and drip-proof housing and computer with installed controlling software. Biodector contains board with two rows of holes for placement of materials under examination and test objects, table with possibility of step-by-step motion; video system interfaced with computer for transfer of images of holes for materials under examination and test objects to monitor and RAM and consecutive calculation of toxicity degree for material under examination; lighting installation with two highlight bars. Video system includes two small-size uncased video cameras with microscope objectives having variable focal distance; step-by-step motion node of the table includes microcontroller connected with step motor and computer serial port. Device is also equipped with three-colour status indicator of biodetector. Quality evaluation of different objects and severity degree of illnesses is carried out based on comparison of multiple calculations of animated test objects in samples within set period of time by means of special computer program. Device allows simultaneous evaluating of large number of different objects and identifying time history of test objects number in one experiment. ^ EFFECT: device is simple and reliable to operate; it does not require start-up operations and high qualification of an operator. ^ 1 dwg |
