The Smoke Combustion analyzer enables easy measurement of flue gas, draft, pressure, ambient CO, and differential temperature.

The Smoke Combustion analyzer combines decades of experience in measuring technology with contemporary smart-touch operation, with Bluetooth® connectivity, robust construction, and e-mailing of reports.

Impressive measuring technology and quality

  • O2 sensor and CO sensor up to 4,000 ppm
  • Testo Bluetooth® Connector.
  • Longer sensor service life thanks to automatic sensor protection
  • Integrated fine pressure
  • Versatile probes and fast probe changes: take advantage of quick-change probes and the multi-functional handle for attaching a variety of probe shafts (each available to order separately). You can for instance use longer probe shafts for flue gas pipes with larger diameters or flexible probes for difficult-to-access measuring points
  • Optionally available probes and accessories for further measuring tasks, such as gas flow pressure measurement, gas pipe testing, differential temperature measurement and ambient CO measurement


Application testo 300

Smart, intuitive, efficient: easy operation in day-to-day work

  • Smart-touch display for intuitive operation of the combustion analyzer: the display responds without delay – just as easy as on your smartphone
  • Get the measurement result faster: clearly structured measurement menus for all relevant measurements
  • Create documentation (including measuring value, measuring location, and customer data) easily on site
  • Save PDF measurement reports directly in the instrument and always have them available
  • Signature function: your customer can sign measurement reports directly on the instrument
  • E-mail measurement reports directly to the office or to customers via WiFi (hotspot)
  • Large 5-inch HD display – enables you to see all the system's parameters immediately
  • Testo interface function for direct data transfer of measuring values to industry/customer-specific software*
  • Ready to use right away: in standby mode, the Next-Gen testo 300 is ready to measure at the touch of a button. Use it right away with the next customer – because you no longer need to wait for the end of the zeroing phase

*Note: the manufacturer has to integrate an interface into the industry software to use the function


Other advantages

  • 10-hour rechargeable battery life: an average measurement period of 2 hours means the combustion analyzer is capable of being used for one week
  • Integrated, extra-strong magnets for easy fixing during the measuring process
