Whether you are a technician servicing diesel engines, or a manufacturer who needs to provide proof of emission values – determining the smoke count is often part of your job. With the smoke tester testo 338, you are ideally equipped for the determination of the degree of blackening in diesel engines. The easy-to-operate, handy measuring instrument records the soot concentration (mg/m3) and the Filter Smoke Number (FSN) or Bosch number for you.
