Ecological Systems and Devices Annotation << Back Field photometric instruments with automatic cleaning of photosensors’ and light sources’ windows Melnichuk O.V., Fetisov V.S. The problem of parasitic deposits on transparent windows of light sources and photosensors in field photometric instruments is described. Various ways to minimize influence of this phenomenon are considered. An original method and the corresponding device for automatic cleaning of measuring cells of field photometric instruments are proposed. The proposed solutions can obtain long period of autonomous operation for such instruments without any service by personnel. Key words: photometric instrument; photosensor; light source; automatic cleaning. E-mail: fet777@rambler.ru
