Development of multichannel photometric sensor

With the development of the computer technique the capability appeared on the basis of personal computer (PC) to design different measurement complexes for laboratory investigations. Sensing devices, computer properly, and data acquisition system (DAS) performing the information exchange are compound parts of the computer measurement complex. Computer measurement complexes are widely used to diagnose gas media by photometric methods. Photoelements matrix as a rule is used as a sensing devices. Photoelement type is chosen as a function of the wave strength and length of the radiation registered. Measurement devices available are mainly based on DAS using the system bus of the computer and are usually differed by redundant, universality.
