Optical Smoke Meter (OSM)
The Rotadata Optical Smoke Meter is the result of co-operative development between Rotadata Ltd. and Rolls-Royce plc. The smoke meter is a fast, reliable and repeatable alternative to the traditional filter paper methods, providing accurate real-time indication of particulate density, directly in SAE (or any other) smoke units.
The Clear Solution for Measuring Smoke Emissions.
To contribute in protecting the world climate from engine smoke emissions a quick and reliable method of measuring them is needed to ensure new engine developments and production engines meet the various international social and legislative requirements.

The Rotadata optical smoke meter (OSM) has been developed to measure such emissions, which are produced by aero engines, gas turbines, and internal combustion engine exhaust gases. Our OSM is a fast, reliable and a repeatable alternative to the traditional filter paper methods, providing accurate real-time indication of particulate density, directly in SAE (or any other) smoke units.
The meter sets new standards in the reliable measurement of low level smoke density in engine emissions and is the result of co-operative development between Rotadata Limited and Rolls-Royce plc. Constructed using the highest quality materials and state-of-the-art electronics, this unique instrument is in a class of its own.
The meter uses light obscuration techniques in a carefully controlled temperature environment and is supplied fully calibrated and ready to connect to your engine emissions sampling system.
