What is it?
The G16 Smoke Density Monitor from Green Instruments is an advanced monitoring system that continuously measures the density of smoke in ship exhaust gases. Specially designed for maritime applications, it helps monitor engine combustion quality and ensure compliance with environmental regulations. By accurately measuring smoke density, engineers can quickly detect irregularities in the combustion process, which supports both environmental protection and more efficient fuel use. The monitor is suitable for various fuel types and engines, and can be installed on both new and existing vessels.

How does it work?
The G16 operates using optical measurement: a light source shines through the exhaust channel, and a detector measures how much light is absorbed by smoke particles in the exhaust. The more smoke particles present, the more light is absorbed, and the higher the smoke density. This measurement is performed continuously, giving the crew real-time insight into smoke emissions. The monitor is built with a robust housing to withstand harsh engine room conditions. It is low-maintenance, easy to install, and requires no calibration after installation.

What problems does it solve?
The G16 Smoke Density Monitor helps ship operators and engineers comply with increasingly strict environmental regulations, such as MARPOL standards for air pollution. By detecting poor combustion early, the system helps prevent violations and fines, saves fuel, and extends the lifespan of engines and exhaust filters. The monitor provides a direct visual indication of smoke emissions, allowing action to be taken before smoke becomes visible on deck or outside the ship—an important factor for a company’s reputation.
