testo 300 Basic – Really smart flue gas measurement

Truly smart flue gas measurement, that’s what testo 300 stands for. The compact flue gas meter is fully controlled via the large touchscreen. You see all the measured values directly without scrolling. The highly scratch-resistant display is housed in a robust plastic instrument housing, which can be relied on even under tough daily working conditions.

There are ready-made menus for the most important measurements to guide you through the work. In addition, the flue gas meter does not know what waiting times or start phases are. It is immediately ready to measure even if it is in standby mode. It handles documentation just as quickly – with the testo 300, reports can be created directly at the measurement site.

  • Ready-made intuitive menus for all relevant measurements
  • 4 strong magnets with rubber coating for material-friendly mounting
  • Ready to measure directly even in standby mode
