Contact Instrument Solutions

Overview

The Testo 338 is an electronic smoke pump that enables the busy combustion engineer to quickly measure the levels of soot an engine is producing during planned or regular maintenance schedules.

Available in two configurations, with or without Bluetooth communications capabilities, the Testo 338 is easy to use, compact, robust fast to operate - by the touch of a button, and can link to printers via it's IRDA port for record retention. Typical applications for the Testo 338 include; diesel power or heating engines; shipping companies and dockyards; industrial engines; mining and prospecting; construction machines and land-moving vehicles.

Features

  • Handy and robust, making it 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
