Innovation: Signaling devices of concentration of gases

Prototype. The invention belongs to gages of concentration of harmful gases. A way of measurement of concentration of gases in which by measurement by receivers of infrared radiation, with the interferential filters which are previously applied on them which wavelength of a transmission is coordinated with the wavelength of own absorption of gas differences of intensity of the streams which passed from a source of infrared radiation through two workers channels in which measuring ditches are placed and behind change of the measured values define concentration of gas. Measuring ditches are made various length, place them in independent working channels, and through measuring ditches pump over gas is analyzed, pump over gas through measuring ditches serially and synchronously with measurement of a difference of absorption of intensity of radiation of the relevant channel. Measurements of a difference of absorption of intensity of radiation at the exit measuring carry out a ditch receivers of infrared radiation, and define concentration of gas from a ratio. Prototype.

Let's consider any options of cooperation.
