Ecological Systems and Devices Annotation << Back Application of photosensor arrays in field photometric devices for monitoring of liquid and gaseous media content Fetisov V.S., Melnichuk O.V. The idea of photosensor array application instead of discrete photosensors in field photometric instruments, such as turbidimeters, is described. Such solution allows to measure medium parameters invariantly relative to dirtying of photosensor’s window. It is important for cases where long automatic operation of the devices without any service of personnel is required. Key words: photometric instrument; photosensor array; cleaning device.
