Testo 338 is an instrument for easy electronic soot count measurement for diesel engines. It records the soot count digitally to one decimal space with constant sampling. 

  • Handy and robust: easily possible to carry to the desired application site
  • Determination of soot concentration (mg/m3) as well as Filter Smoke Number (FSN) or Bosch number
  • Easy one-handed operation
  • Direct analysis and display of measurement values, optional on-site printout of data with Testo fast printer
