Testo 338 Smoke Tester

Overview

The Testo 338 smoke tester is a portable instrument for particle and soot emissions from diesel engines and industrial processes. Compact enough for a toolbox, it measures Filter Smoke Number (FSN) / Bosch number and soot concentration without installing a permanent system—useful in plants, ships, shipyards and mines.

Real-time readings and a clear display help confirm injection timing after service, support environmental compliance work, and check diesel particulate filters. Optional IR printout supports on-site documentation.
