Green Instruments G4130 NOx/O2 Analyzing System

The Green Instruments G4130 NOx/O2 Analyzing System is a gas analyzer, designed to monitor NOx and O2 concentrations directly in exhaust gases. The system consists of the NOx/O2 analyzer, a sampling board and a diffusion probe with a sensor for the precise monitoring of NOx and O2 levels. The G4130 provides reliable data for SCR/combustion optimization as well as data for regulatory environmental reporting requirements, thus helping to ensure environmental compliance. The system is simple to install and integrate on board vessels.

The diffusion probe on the G4130 analyzer ensures that the gas is diffused to the measuring chamber, making it suitable for most marine applications.

The G4130 Analyzing System uses a zirconium dioxide sensor with multiple diffusion cells. The sensor is small and robust, placed directly in the probe head and operates reliably in harsh and tough marine conditions. The sensor technology allows measurements on wet basis at high temperatures, and it avoids the disadvantages of sample lines, sample systems, and converters. An extra advantage of the G4130 NOx/O2 analyzing system is the interface via touchscreen, making it extremely user-friendly for the crew.

When the Green Instruments G4130 is used in combination with an emissions abatement system such as a selective catalytic reduction (SCR) or exhaust gas recirculation system (EGR), the fuel combustion, urea injection, and other operating parameters will constantly be optimized. Real-time emission data provided by the NOx analyzer is crucial for engine and equipment diagnostics.
