| titleOfInvention | Photocolorimeter-reflectometer |
| abstract | FIELD: instrument methods of chemical analysis, applicable for photometric measurement of colored and turbid solutions, colored and gray surfaces. SUBSTANCE: photocolorimeter- reflectometer has two optopairs containing radiation sources - light emitting diodes and photodetectors connected in differential circuit and forming two optical channels. One of the channels is made as a reflection channel and makes up the reflectometer. The light-emitting diodes and photodetectors in the channels are located at an angle providing for the maximum getting of radiation reflected from the sample under analysis onto the photodetector. The instrument is provided with replaceable attachments for operation with gaseous, liquid and solid samples. EFFECT: simplified measuring circuit, enhanced sensitivity of measurements and capability of operation with liquid and gaseous media. 5 cl, 4 dwg |
