For Vehicle Gas and Catalytic Emission Gas
NH3 Gas Analyzer
MODEL Bex-1000NH

BCO-611 Fast and Accurate Direct Measurement of NH3 in Exhaust Gas by Microwave Absorption Method

Today, the development of the Urea SCR system is strong focused as anew technology, which can help to reduce NOx in exhaust gas from diesel engine.
Bex-1000NH makes impossible to analyze the accurate reaction mechanism, which is supported by high sensitivity and high speed response.



●Fast response and high accuracy by micro wave
　 method
●Reacts directly to the NH3 gas
　 (It is not a conversion method of NH3 to NO...
　 like CLD)
●Fine cross interference
●Wide range and fast response
　NH3 T10-90% less than1.5sec (at 500ppm)
