Infrared Flue Gas Analyzer

We hold expertise in developing upgraded Infrared Flue Gas Analyzer. These products are manufactured with utmost precision in adherence with the defined parameters of the industry. Designed to perfection, these products are measures the gas concentration of CO, CO2, CH4 and C3H8 based on NDIR technology, concentration of H2 based on TCD and concentration of O2 based on ECD. NDIR principle is based on measurement of absorption spectrum intensity of wavelength of infrared light through a gas, the attenuation intensity of light dependent on the gas density in compliance with Lambert – Beer’s Law.n Our products are suitable to used in industries such as iron & steel, ferro alloys during smelting process gas analysis of sponge iron including blast furnace, coke oven, heat treatment, gas furnace, calcium carbide furnace, flue gas composition measurement in cement shaft kiln, gas analysis of straw biomass gasification process and analysis of industrial gases in environmental protection.

The Infrared Flue Gas Analyzer that we offer is used in different industrial sectors including iron and steel, sponge iron and ferro alloys in order to check the concentration of gases like oxygen, hydrogen, carbon monoxide and carbon dioxide. This equipment provides accurate measurement results.

Infrared Coal Gas Analyzer

We offer the best quality Infrared Coal Gas Analyzer to our clients at an affordable price. The equipment that we offer is highly accurate and offers authentic results in the measurement of the concentration of gases like hydrogen, oxygen and carbon dioxide. The equipment is reliable enough and can be used without any concern.
Infrared biogas analyzer measures the gas concentration of CO2, CHbased on NDIR technology,concentration of H2S and O2based on ECD (simultaneous measurement of 4 gases). Single Source duel beam non dispersion infrared (NDIR) principle is based on measurement of absorption spectrum intensity of wavelength of infrared light through a gas, the attenuation intensity of light dependent on the infrared gas concentration. This online product is used to detect the concentration of CO2, CH2, H2S and O2 produced in the biogas and landfill gas. Main applications are biogas plants anaerobic digestion, sewage treatment plants, sludge digestion, bio methane production plants, landfill sites, etc.
