Model G4100 - NOx/O2 Analyzer System
From NOx Emissions
Green Instruments’ NOx analyzer – the G4100 NOx/O2 Analyzing System – is a direct in situ gas analyzer that monitors NOx and O2 concentrations in emission gas. The NOx analyzer provides a cost-effective solution to help fulfill tightening emission regulations as well as supporting the most effective operation for all types of combustion processes. It is designed to meet the challenging requirements for monitoring the inlet and outlets of selective catalytic reduction systems (SCR) on all types of combustion sources.
New Zirconia Sensor Technology Allows Real-time Measurements
The G4100 NOx analyzer uses a zirconium oxide (ZrO2) sensor with multiple diffusion cells. The sensor is small and robust and can be installed directly on the stack without special protection.
The technology of the GI NOx analyzer allows real-time measurement of NOX and O2 on wet basis at high temperatures. This avoids sampling lines and multiplexing systems, coolers and converters with all their disadvantages.
The simple plug‘n’play design makes it easy and cost-effective to install, operate, and maintain. A complete system includes an automatic back-flushing ejector probe that is connected to an analyzing board with analyzer and air supply and calibration gas ports.
NOx Analyzer Complies with the NOx Technical Code 2008
The G4100 NOx analyzer is designed in compliance with the NOX Technical Code 2008 and the analyzer is type approved by Lloyd’s Register. It provides you with real time data on NOx in ppm and O2 in percent. This data can be integrated in any system. Green Instruments offers the G49xx family for this purpose.

How to Comply with Marpol Annex VI
Using the G4100 NOx analyzer in combination with an emissions abatement system like a selective catalytic reduction or exhaust gas re-circulation system will allow constant optimization of the engine and other operating parameters.
Combining a NOx analyzer with an emissions abatement system will provide up to 5% fuel savings and at the same time comply with Tier II emission requirements of Marpol Annex VI. Even with Tier II engines, continuous monitoring of NOx will allow using or bypassing the after-treatment equipment to achieve Tier III while sailing in and out of the emission control areas (ECA).
Real time emission data from the NOx analyzer provides important input for diagnostics of both the engine and the after-treatment equipment.
