ANALYSERS Infrared gas analyser DID 1.000 – ??  ASSIGNMENT - permanent monitoring of pre-explosion ratio of hydrocarbon gases at fabrication systems, logging of diurnal, week-long and monthly emissions at a unified control house and in a relay room directly.
MODE OF FUNCTIONING – measuring of IR absorption in hydrocarbon gases at two wavelengths on path of its dessimination from transmitter to receiver.
