Product details
LIMAS21 Nitrogen Oxide&Ammonia Analyzer
LIMAS 21 Nitrogen Oxide+Ammonia High Concentration Analyzer is based on UV-RAS (Ultraviolet Resonant Absorption Spectroscopy) method, which selectively absorbs the measured gas in the UV and visible spectral range of λ=200-600nm (Limas21 UV). Gas filter correlation and wavelength comparison techniques are used to measure NO, NO2, and NOxyiji NH3.
The instrument does not require a converter and can directly measure NO and NO2 simultaneously to calculate NOx. The concentration of NH3 can be directly measured.
Measurement object NO,NO2，NOx,NH3 Purpose: Determination of the content of nitrogen-containing compounds such as NO, NO2, NOx, NH3, etc. in special gases Can be used for analysis of automobile exhaust and flue gas emissions After adding NH3 measurement, it can be used for catalyst and nitrogen oxide emissions after ammonia denitrification Can be used for testing damp samples with a dew point temperature of 65 ° C, with built-in zero point gas without the need for a standard gas cylinder measuring range NO: 0-5000ppm NO2: 0-5000ppm NH3: 0-500ppm Maximum range ratio 1：20 Linear deviation ≤1% repeatability ≤0.5% zero drift 2% F.S. per week Span Drift ≤1% Detection limit ≤1% f.s.
