Its working principle is based on the fact that gases such as NH3, CO, CO2, CH4, SO2, NOX, etc. all have their own corresponding (different) body absorption characteristics of specific wavelengths of radiation energy in the infrared band. The degree of absorption of radiation energy at a specific wavelength depends on the corresponding concentration of the measured gas. ● The infrared radiation energy absorbed by the measured gas passes through a specific wavelength filter and acts on the pyroelectric detector, that is, it is converted into an electrical signal corresponding to the concentration value of the measured gas. Then the electrical signal is compared with a constant reference electrical signal equivalent to zero (N2) of the measured gas, and the difference is amplified, detected, optical path balanced, zero, end point adjustment, linearization correction, etc., and the percentage concentration of the measured gas is displayed on the instrument indicator. Working principle: Infrared gas analyzers are non-spectral infrared analyzers. Its working principle is based on the selective absorption of infrared rays by certain gases. The instrument uses an advanced single light source, a single tube separated by half a gas chamber, and a new pyroelectric detector with high stability and reliability. Compared with similar products, the biggest features of this product are high stability (the instrument works stably for a long time and the zero point drift is small), high reliability (solid detector) and high selectivity. Purpose and application areas: It is used to continuously measure the relative concentration of gases and is widely used in petroleum, chemical industry, fertilizer, environmental protection, building materials, metallurgy, agriculture, scientific research and medical and health fields. Main technical indicators: Can be used to measure: NH3, CO, CO2, CH4, SO2 and other gases. Response sensitivity: ≤0.2%FS repeatability: ≤1%FS zero drift: ≤±1%FS/7d range drift: ≤±1%FS/7d linear error: ≤±1%FS response time:

The essence of the 2nd floor’s explanation of non-dispersion is as follows:: Gases all have their own corresponding (different) body absorption characteristics of radiation energy of specific wavelengths in the infrared band. The degree of absorption of radiation energy at a specific wavelength depends on the corresponding concentration of the measured gas. ● The infrared radiation energy absorbed by the measured gas passes through a specific wavelength filter and acts on the pyroelectric detector, that is, it is converted into an electrical signal corresponding to the concentration value of the measured gas. Then the electrical signal is compared with a constant reference electrical signal equivalent to zero (N2) of the measured gas, and the difference is amplified, detected, optical path balanced, zero, end point adjustment, linearization correction, etc., and the percentage concentration of the measured gas is displayed on the instrument indicator.
