MEXA-1170NX
Overview
In the forefront of powertrain development, de-NOx technology for the conversion of harmful NOx to harmless N2 is a key area for researchers today. This is where HORIBA's new MEXA-1170NX analyzer leads the way. It is the ideal tool for measuring NH3 in the development of various NOx reduction technologies such as selective catalytic reduction (SCR), Lean NOx Traps (LNT) and three way catalysts. It measures NH3 in real time with high sensitivity using twin chemiluminescence (CLD) detectors with an NH3 oxidizing oven. In addition to standalone measurement of NH3, NO and NOx, it can be integrated as an additional analyzer with the MEXA-7000 series.
Features
Highly sensitive,real-time measurement of NH3 and NOx, or NO2, NO and NOx. By means of two heated-type chemiluminescence (CLD) detectors with anNH3 oxidizing oven, either NH3 or NO2 can be measured with high sensitivity in real time by calculation of the difference of NO readings from two detectors (one without a converter). The MEXA-1170NX can measure NH3 and NOx, or (optionally) NO2, NO and NOx. Remote operation from MEXA-7000. The MEXA-1170NX can be used either as a standalone NH3 analyser or integrated, via the MCU, into a MEXA-7000 system for remote control and monitoring.
